SINGLE LAYER HIGH GAIN MICROSTRIP PATCH ANTENNA

Abstract

A high-gain microstrip patch antenna with a single layer and one patch that is dual-polarized is shown in this letter. The design begins with a high-gain, cross-shaped microstrip patch antenna. To provide light on the workings and theoretical constraints, an antenna array model is constructed. In order to lower the sidelobe level, the middle portion of the cross-shaped patch is also deleted. The next step is to use the modified cross-shaped patch as the basis for a high gain antenna with dual polarization. To further enhance isolation, a cross-shaped strip is also included. We finish by making and measuring a prototype to demonstrate our concept. From 4.74 to 4.83 GHz, the suggested antenna has an impedance bandwidth of 1.8% and a peak realized gain of 12.47 dBi, according to the tests. Two ports are more than 24.8 dB apart in the passband. The suggested antenna only measures 1.44λ0 x 1.44λ0 × 0.024λ0 in total dimensions.
