Half-Arrow Miniaturized Antenna for Inter-Satellite Communications Using HMSIW

Abstract

The inter-satellite communication is highly demanded antennas to achieve a compact size, circular polarization low profile, high gain, and specific radiation patterns. In this paper, a novel HMSIW slot antenna combines a significant bandwidth enhancement and small footprint for inter-satellite communications at C-band. The designed antenna has the capability of achieving a reduction of size with nearly 50% in comparison to conventional SIW s. The simulation results shows that the proposed antenna has an impedance bandwidth of 3.8%, an average gain of 5.26 dB and radiation efficiency of 93%.
