A low-profile printed dipole antenna (PDA) backed by broadband rhomboid artificial magnetic conductor (AMC) is introduced for vehicular wireless communications. Firstly, a suggested PDA with a pair of the microstrip E-shaped dipoles is fed by an E-shaped microstrip feedline to expand the bandwidth in the measured range of 5.5-6.96 GHz (S11≤ -10 dB)...

... Similarly, many antennae [8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25] were developed with different techniques to increase the isolation, decrease the mutual coupling, or enhance the parameters like ECC, but all of these antennas have a limitation in terms of throughput and ECC which is necessary for the proposed applications of AWS and WBAN. Here we propose a MIMO antenna with low coupling and ECC without any additional structure in the antennas with dual frequencies of operation. ...
... Dual-function/Multi-functional antennas with planar structure have become very popular to realize multiband characteristics in several fields of wireless communication. Printed slot antenna structures have been widely investigated for obtaining dual-band/multi-band response due to their attractive properties such as low profile, easy fabrication and compact size [1][2][3][4]. Many of these antennas have one major disadvantage of producing bi-directional radiation which is undesired in certain applications. ...
In this paper, low profile cavity-backed cross shaped slot antenna using substrate integrated waveguide (SIW) technology is proposed for obtaining quad-band response. In order to generate four distinct frequencies, a crossed slot is etched on the back of the dielectric substrate and three balanced shorting vias (metallic vias) are included across the longitudinal slot. Furthermore, the electric field distribution has been utilized for understanding the working principle of the proposed design. Balanced shorting vias modify the current distributions of the cavity, which consequently produces two resonant frequencies in X-band and two more resonant frequencies in Ku-band. Finally, the proposed quad-band antenna is fabricated using printed circuit board (PCB) technology and the results are experimentally verified. With the height of 0.026λ0, the measured results show that the proposed design resonates at 8.6 , 10.2 , 13.2 , and 14.8 GHz and exhibits a –10 dB impedance bandwidth more than 150 MHz at corresponding frequencies. The proposed antenna attains a peak gain of more than 6 dBi at the corresponding resonant frequencies, respectively. Those amicable characteristics, e.g., low profile, uni-directional radiation pattern, ease of fabrication, quad-band response and moderate gain, make the proposed antenna suitable for both radar and satellite systems.
