A rectangular microstrip patch antenna with capacitive feeding is presented here. To overcome various problems in other feeding, capacitive feeding technique has used. The designed antenna consists of stacked arrangement of a rectangular radiating patch and a small feeding strip which is fed by coaxial feeding probe. Using capacitively fed rectangu...

... a microstrip patch antenna radiates normal to its patch surface, the far field components E (φ=0 o ) and E (φ=90 o ) for the two principal planes, E -and H -planes respectively, would be important. Figure-6 shows the normalized value of the radiation pattern occurs at 2.427GHz. It can be noticed that the pattern in both planes have uniform shape (symmetric with respect to the zenith). ...

In this paper, a deformed radiating element is proposed to design a comb-line array antenna for low sidelobe levels in the millimeter-wave band. To design the comb-line array antenna with a low sidelobe level, the use of the wide radiating elements for a relatively large radiation conductance is required. However, the conventional rectangular radia...
Microstrip antenna with circular polarization can be applied for many applications. Some microstrip antenna with square, circular, triangular, and hexagonal shape has been designed to get return loss, axial ratio, and radiation performance. We compare twelve microstrip antenna by maintaining its substrate dimension, feeding shape, and outer patch d...

... Bandwidth enhancement can also be achieved by modifying the feed networks (elements) such as meandered probe [15] or changing the probe to T-shape [16] or L-shape [17]. However, many of these geometries use multiple metal/dielectric layers for enhancing the impedance bandwidth which poses fabrication and assembly problems. ...
Microstrip antennas are very promising due to their integration capability, but lack of bandwidth. In many communication applications they need to operate in broadband. A high gain wideband microstrip patch antenna is presented in this paper. The design adopts contemporary techniques; direct coaxial probe feeding, inverted patch structure with air-filled dielectric, and E-shaped patch. The integration of these techniques leads to a new patch antenna with a low profile as well as useful operational features, as the broadband and high gain. The proposed antenna shows a wideband behavior. It is found that antenna attains impedance bandwidth of 41.5% (VSWR ≤ 2) in the frequency range (2.1GHz-3.2GHz). The achievable gain is 9.4dB at 2.42GHz. A parametric study has been carried out in the investigation. A conventional rectangular patch antenna using RT-Duroid 5880 with ε r = 2.2 and thickness 1.6mm at operating frequency 2.42GHz is used as a reference. The simulated results obtained from MW-Office 2006 simulation software.
