Inset Fed PBG Substrate with DGS Slotted Rectangular Microstrip Patch Antenna Design for C-Band Satellite Applications

An inset fed slotted rectangular microstrip antenna is proposed and researched in this paper using Photonic Band Gap (PBG) substrates with Defected Ground Structure (DGS). Rogers RT/duroid 5880 (tm) which is utilized as substrate material whose dielectric steady is 2.2. Firstly, using HFSS software, a normal rectangular microstrip patch antenna is designed and its contribution is noticed. Secondly, on the patch, many circular slots with equal distance and diameter are made. Thirdly, many circular air holes are created on the slotted rectangular microstrip antenna’s substrate with equal distance and diameter to present PBG substrate and afterwards the performance of that antenna is noticed. Finally, by making circular defects of equal distance and diameter on the ground plane of previously designed antennas, DGS is generated. This antenna gets the best exhibitions among the past three designed. The proposed antenna's return loss, bandwidth, gain and directivity are -38.7 dB, 441.7 (5.0556- 5.4973GHz) MHz, 9.0828 dBi and 9.2161 dBi respectively. At a frequency of 5.2765 GHz, which can be used as C-band satellite applications, the proposed antenna is resonated.
