A simple and single element wide slot dipole loaded shorted rectangular microstrip antenna has been proposed and investigated experimentally for broad impedance bandwidth and improved cross polarized (XP) radiation compared to maximum co‐polarized (CP) gain without changing the co‐polarized (CP) radiation pattern. Around 23‐35 dB isolation between CP and XP radiation along with 25% impedance bandwidth is achieved with the proposed structure. The measured gain of the antenna is around 6.2 dBi over the entire band. The present antenna is very simple and easy to manufacture. Unlike the other structures, the present one is free from back radiation in terms of XP fields. The design of the antenna structure is theoretically justified and rigorously analyzed. The present investigation provides an insightful, clear visualization‐based understanding of the concurrent improvement in both the impedance bandwidth and XP performance with the present structure.

In this paper a Wang shaped patch antenna has been designed for wireless communication systems application such as cellular telephone and radar for the frequency range between 0.7575GHz to 1.2121GHz. The maximum bandwidth, gain, return loss, directivity and efficiency of proposed antenna is 46.16%, 5.2dBi, -25dB, 7.60 dBi and 93% respectively. The antenna design offers high bandwidth, low profile which is feed by coaxial probe at 64.75mm, 60.135mm and height of the substrate thickness is 1.6mm.

A simple rectangular microstrip antenna with triangular slotted ground plane has been studied both theoretically and experimentally to improve shortcomings like low gain (5-6 dBi), narrow bandwidth (3%-4%), and poor copolarization (CP) to cross-polarization (XP) isolation, i.e. polarization purity (typically 10-12 dB), of conventional rectangular microstrip patch antennas. By placing two pairs of triangular shaped slots on the ground plane just below the nonradiating edges of the patch, high gain (around 9 dBi) and more than 22 dB polarization purity over a wide elevation angle has been achieved. The proposed antenna covers almost the full X band of frequency from 9.55 GHz to 11.43 GHz while resonating at 10.35GHz (i.e. impedance bandwidth of 17%), so the proposed antenna offers improved gain, impedance bandwidth, and polarization purity simultaneously as compared to conventional rectangular microstrip antennas. Parametric studies have been documented to achieve the optimum defect dimension. The specialty of the proposed antenna is that the gain and radiation pattern is quite stable in the entire operating frequency band, along with its attractive gain, impedance bandwidth, and polarization performance. The simulated and measured results show close resemblance to each other. The proposed geometry is quite simple and easy to fabricate and therefore may be ideal for applications where high gain, stable radiation characteristics, and wide impedance bandwidth along with high copolarization to cross-polarization isolation over wide elevation angles are required.
