Abstract:
In this paper a structure of microstrip antenna which is operated on 8.28 GHz is proposed. The given antenna has a ground which defected by the
slots structure (DGS) with some modification in the patch and tapering in the feed line. The impedance bandwidth can be increased by using DGS technology. The proposed antenna is used for x-band application such as radio location. The return loss at the frequency 8.28 GHz is -47.82 dB. The gain at the correspondence frequency is 3.76dBi. The antenna shows the improvement in impedance bandwidth and gain is sufficient high for the complete x-band.
