Dedicated short-range communications (DSRC) is an important wireless technology for current and future automotive safety and mitigation of traffic jams. In this work, we have designed a Coplanar waveguide microstrip patch antenna with linear, upper and bottom and side slots for application in DSRC.

Various parametric analyses such as the current distribution, reflection coefficient, radiation pattern on E- and H-plane as well as the realized gain (dB) were performed. The results were obtained by simulation using high-frequency structure simulator tool.

An approach is presented to enhance the isolation of a two-port Multiple Input Multiple Output (MIMO) antenna using a decoupling structure and a common defected ground structure (DGS) that physically separates the antennas from each other. The antenna operates in the 24 to 40 GHz frequency range. The innovation in the presented MIMO antenna design involves the novel integration of two arc-shaped symmetrical elements with dimensions of 35 × 35 × 1.6 mm3 placed perpendicular to each other. The benefits of employing an antenna with elements arranged perpendicularly are exemplified by the enhancement of its overall performance metrics. These elements incorporate a microstrip feed featuring a quarter-wave transformer (QWT). This concept synergizes with decoupling techniques and a defected ground structure to significantly enhance isolation in a millimeter wave (mm wave) MIMO antenna. These methods collectively achieve an impressively wide bandwidth. Efficient decoupling methodologies have been implemented, yielding a notable increase of 5 dB in isolation performance. The antenna exhibits 10 dB impedance matching, with a 15 GHz (46.87%) wide bandwidth, excellent isolation of more than 28 dB, and a desirable gain of 4.6 dB. Antennas have been analyzed to improve their performance in mm wave applications by evaluating diversity parameters such as envelope correlation coefficient (ECC) and diversity gain (DG), with achieved values of 0.0016 and 9.992 dB, respectively. The simulation is conducted using CST software. To validate the findings, experimental investigations have been conducted, affirming the accuracy of the simulations.

(1) Background: Cooperative Intelligent Transportation Systems (C-ITS) will soon operate using 5G New-Radio (NR) wireless communication, overcoming the limitations of the current V2X (Vehicle-to-Everything) wireless communication technologies and increasing road-safety and driving efficiency. These innovations will also change the RF exposure levels of pedestrians and road-users in general. These people, in fact, will be exposed to additional RF sources coming from nearby cars and from the infrastructure. Therefore, an exposure assessment of people in the proximity of a connected car is necessary and urgent. (2) Methods: Two array antennas for 5G-V2X communication at 3.5 GHz were modelled and mounted on a realistic 3D car model for evaluating the exposure levels of a human model representing people on the road near the car. Computational simulations were conducted using the FDTD solver implemented in the Sim4Life platform; different positions and orientations between the car and the human model were assessed. The analyzed quantities were the Specific Absorption Rate on the whole body (SARwb), averaged over 10 g (SAR10g) in specific tissues, as indicated in the ICNIRP guidelines. (3) Results: the data showed that the highest exposure levels were obtained mostly in the head area of the human model, with the highest peak obtained in the configuration where the main beam of the 5G-V2X antennas was more direct towards the human model. Moreover, in all configurations, the dose absorbed by a pedestrian was well below the ICNIRP guidelines to avoid harmful effects. (4) Conclusions: This work is the first study on human exposure assessment in a 5G-V2X scenario, and it expands the knowledge about the exposure levels for the forthcoming use of 5G in connected vehicles.

This paper introduces a compact Multiple input Multiple output (MIMO) antenna system for vehicular application in the sub-6GHz 5G systems that operates in the middle and high frequency bands from 1.71GHz to 5GHz. The proposed design consists of two symmetrical raised printed monopoles on Flame Retardant 4 (FR4) dielectric material with Partial Ground Plane (PGP) structure to improve bandwidth impedance and achieve higher isolation across the operating frequency range. The design is an excellent candidate to be implement in a shark-fin housing due to its low-profile characteristics and good electrical performance. The antennas are simulated using HFSS software and then prototypes are made and measured on a one-meter rolled-edge ground plane in an anechoic chamber. The electrical performance results of the proposed design and its MIMO characteristics are discussed and plotted in terms of Voltage Standing Wave Ratio (VSWR), passive isolation, radiation patterns, radiation efficiency, linear average gain (LAG), Diversity Gain (DG), and Envelope Correlation Coefficient (ECC).

Friction stir welding is commonly used to join dissimilar materials that are difficult to weld when using conventional methods. Weld joints of dissimilar aluminum alloy 6061 and mild steel were obtained by friction stir welding using a variation of parameter values. Macroscopic examination indicated successful bonding between the two materials although some defects may result in decreased joint strength. Further microstructure analysis revealed grain refinement from stirring action of tool pin with steel particles randomly scattered in plasticized aluminum. Chemical composition analysis identified Al-rich intermetallic compound Fe2Al3 at the weld interface. Thicker intermetallic layer was influenced by higher heat input from increased rotation speed and decreased welding speed. Maximum hardness was measured at the interface, indicating formation of a brittle intermetallic compound.

The purpose of this study is to investigate the effect of needle size and substrate to needle height by measuring the droplet volume and epoxy covered area in encapsulation process of LED packaging. Five needle gages (16G, 18G, 21G, 22G, and 23G) were used in this experiment. Average volume of epoxy drops was determined for each size of needle. Experimental data shows that droplet volumes are directly related with the needle diameter. Optimum covered area by the epoxy encapsulation was found at the needle tip to substrate distance at 3.240 mm for the 16G needle. These findings are relevant and helpful for controlling the amount of epoxy, encapsulation area, and the encapsulant shape in encapsulation process of LED packaging.KeywordsDroplet volumeEpoxy dropNeedle sizeEncapsulationLED packaging

Most works in antenna design are focussed on the results for the fundamental antenna parameter that can be achieved in the antenna simulator. For further investigation, the antenna must be fabricated, measured and installed to observe the propagation results. This work involves antenna characterisation and a 3D propagation model. Characterisation of the antenna for the transmitter and receiver is for 28 GHz frequency. The input for the computation of the propagation model is using the radiation pattern from the designed antenna. The antenna performance is analysed in different mobile user antenna orientations in vertical and horizontal array configurations. Results show that the propagation performance for the horizontal orientation for the user equipment antenna is outperformed compared better as the downlink SNIR receive power is 45 dBm, 10 dBm higher than the vertical orientation.KeywordsMillimetre waveAntenna rotation3D propagation modelChannel model

Various multiple-input multiple-output (MIMO) antenna systems for automotive applications are presented in this paper using two uniquely designed elements: 1) a low profile wideband Planar Inverted-F antenna (PIFA), and 2) a compact wideband monopole in the sub-6 GHz 5G systems and Vehicle-to-Everything (V2X) communications that cover the frequency range from 617 MHz to 6 GHz. The proposed MIMO systems can be used in a low-profile or shark fin style housing placed on the vehicle’s roof. Each MIMO system achieves satisfactory performance across the whole band with suitable physical dimensions. The envelope correlation coefficient (ECC) and diversity gain (DG) are calculated using MATLAB in each MIMO configuration as they represent the two key factors in the MIMO performance. Simulation results are presented along with measured data on a 1-meter rollededge ground plane (GND) and on a vehicle’s roof from properly cut metal sheet prototypes. The results are discussed in terms of VSWR, passive isolation between elements, combined radiation patterns, port-efficiencies, ECC, and DG.
