Synopsis:

In this paper, a single layer wideband, probe fed modified U-slot microstrip patch antenna is designed for four-band communication system. The proposed antenna has impedance bandwidth of 28.57%(1.2 -1.4 GHz), 14.28%(2.6-3.03 GHz), 5.12%(5.7-6.05 GHz) and 8.9%(7.5-8.2 GHz) at center frequency 1.4 GHz, 2.8 GHz, 5.85 GHz, 7.85 GHz, with gain of 4dB, 10.4dB, 6.1dB, and 10dB. High gain of 10.4dB and 10dB is achieved at center frequency 2.8GHz and 7.85GHz respectively which is applicable for radar application and satellite application. The proposed antenna is designed on a single layer substrate Arlon AD250A with defected ground plane. Antenna is designed and simulated using HFSS v13 software.
