Abstract

The shape of the radiating patch exerts influence greatly on the performance of the microstrip patch. The vital target of this research article is to constitute the microstrip antennas of Circular and Pentagonal patches on FR4 substrate employing partial ground that notably lower the shape complication as a consequence of the antenna size reduction combined with a profitable radiation efficiency on the basis of the center frequency of 8.5 GHz. The specification of return loss, VSWR, gain, directivity, radiation pattern, and the radiation efficiency of the antenna are investigated using ANSYS HFSS 13.0 software which reveals beneficial outcomes of dual - band over the entire band frequency range of 5-15 GHz relating with the earlier analysis. The triangular patch antenna is detected far well compared to the alternatives which is achieved the best gain of 2.2 dB, 6.8 dB, minimum return loss of 19.0144 dB, 34.5612 dB, enhanced bandwidth of 0.50 GHz, 1.15 GHz, and the higher radiation efficiency of 81%, 94% at 9 GHz, 12.34 GHz respectively. This is applicable for Marine Radar communication (SART), productive Satellite Communications, and also it is the best candidate for weather monitoring, defense and military purposes in Wireless Communication applications.
