摘要

提出了一种具有s型槽的小型化圆极化微带天线，用于双频工作。s形槽被切割到方形贴片散热器的中心。相对于2.50 GHz和2.85 GHz，下、上频段10db回波损耗带宽分别为15%和3.5%，3db轴比带宽分别为3.6%和1.1%。在2.5 GHz时，整体天线尺寸为0.458λo × 0.458λo × 0.095λo。

Microstrip antenna with S-shaped slot for dual-band circularly polarized operation

A compact circularly polarized microstrip antenna with an S-shaped slot is proposed for dual-band operation. The S-shaped slot is cut onto the centre of a square patch radiator. The measured 10-dB return loss bandwidths for lower and upper bands are 15% and 3.5%, and 3-dB axial-ratio bandwidths are 3.6% and 1.1% with respect to 2.50 GHz and 2.85 GHz, respectively. The overall antenna size is 0.458λo × 0.458λo × 0.095λo at 2.5 GHz.
