摘要

提出了一种用于2U立方体卫星通信的小尺寸高增益缝隙天线。主要的想法是使用CubeSat表面在天线下方12毫米处的金属部分作为反射器，将反向辐射重新定向到前方。这导致对后瓣辐射的实质性抑制，从而显著增加天线的总增益。仿真结果表明，该天线的增益为9.39 dB, b-10 dB宽带宽为370 MHz (2.53 ~ 2.90 GHz)，谐振频率为2.7 GHz时回波损耗为- 22 dB。

High Gain Slot Antenna with Reflector for 2U CubeSat

A small size and high gain slot antenna is proposed for 2U CubeSats communications. The main idea is to use a metallic part of2U CubeSat's surface at distance of 12 mm below the antenna as a reflector to redirect the back radiation forward. This leads to a substantial suppression of back lobe radiation and hence significant increase of the antenna total gain. The simulation results show that the antenna achieves a superior gain of 9.39 dB, wide b-10 dB bandwidth of 370 MHz (2.53-2.90 GHz) and return loss of −22 dB at a resonant frequency of 2.7 GHz.
