摘要

提出了一种用于立方体卫星的低轮廓、高增益、cpw馈电的缝隙天线。所提出的天线背后有一个低轮廓的金属反射器。利用腔体反射器可以显著提高增益，减少后瓣辐射。天线的紧凑尺寸为36×36 mm2，这意味着它与任何CubeSats标准结构兼容。我们在一颗2U CubeSat (10cm×10cm×20cm)上模拟了天线。结果表明，在2.45 GHz期望频率下，天线阻抗匹配良好，回波损耗为- 30 dB，阻抗带宽为- 10 dB，为109 MHz (2.391-2.50 GHz)，总增益为8.62 dB。

A low profile high gain CPW-fed slot antenna with a cavity backed reflector for CubeSats

A low profile, high gain, CPW-fed, slot antenna is proposed for CubeSats. The proposed antenna is backed with a low profile metallic reflector. The cavity reflector is utilized to significantly improve gain and reduce back lobe radiation. The antenna has a compact size of 36×36 mm2, meaning it is compatible with any CubeSats standard structure. We have simulated the antenna on a 2U CubeSat (10cm×10cm×20cm). Our results show that the antenna achieves good impedance matching with a return loss of −30 dB at the desired frequency of 2.45 GHz, a −10-dB impedance bandwidth of 109 MHz (2.391–2.50 GHz) and has a total gain of 8.62 dB.
