Numerical Experiment of Adding Patch Elements to X-band Microstrip Antennas

This paper compares single microstrip antenna designs and microstrip arrays used for Manpack Radar with X-band frequency. Antenna array configurations were investigated for 1x2, 1x4, and 1x32 elements. A gain increase is required for each additional patch element. Patch dimensions are set at 9.17 x 10.10 x 0.035 mm. The parameters needed are X-Band frequency with gain >15 dBi, beamwidth angle of ≤5°, and bandwidth of more than 60 MHz. The simulation results show a good match with the target required for the 9.3 GHz frequency. The largest gain value numerically is obtained on the antenna with 32 patches, which is 17.1 dBi.
