High Gain Patch Antenna Array with Parasitic Elements for CubeSat Applications

In this paper we present a high gain multiband patch antenna array (PAA) for 3U and 6U CubeSats. The parasitic elements (PEs) are incorporated to enhance the antenna total gain and to achieving good impedance matching. We have simulated the proposed antenna in the High Frequency Structure Simulator (HFSS). Our results show that the proposed antenna achieves a high gain of 11.31 dB (> 6 dB) at 8.15 GHz, small reflection coefficient (S11) of -40 dB and -32 dB at operating frequencies 8.15 GHz (X-band) and 13.01 GHz (Ku-band) respectively.
