Abstract

A low-profile, broadband, circularly polarized (CP) patch antenna is presented. It consists of a driven patch using a loop feeding structure with the purpose of producing the CP radiation. The driven patch is surrounded by eight parasitic patches to broadening the antenna bandwidth. A metasurface, which is a periodic array composed of 10 × 10 square metallic plates, is inserted into between the patches and the ground plane in order to minimize the antenna size. The optimized antenna, with dimensions of 100 mm × 100 mm × 4 mm (0.7λo × 0.7λo × 0.028λo at 2.1 GHz) achieves an impedance matching bandwidth of 27.3% (1.9 – 2.5 GHz), a CP radiation bandwidth of 11.76% (2.00 – 2.27 GHz), the peak gain of 6.9 dBic, and a radiation efficiency of 76%.

利用超表面最小化圆极化贴片天线

提出了一种低轮廓、宽带圆极化(CP)贴片天线。它由一个驱动的贴片组成，采用环形馈电结构，目的是产生CP辐射。驱动贴片周围有8个寄生贴片，以扩大天线带宽。为了减小天线尺寸，在贴片和地平面之间插入一个由10 × 10方形金属板组成的超表面(metassurface)。优化后的天线尺寸为100 mm × 100 mm × 4 mm (0.7λo × 0.7λo × 0.028λo, 2.1 GHz)，阻抗匹配带宽为27.3% (1.9 ~ 2.5 GHz)， CP辐射带宽为11.76% (2.00 ~ 2.27 GHz)，峰值增益为6.9 dBic，辐射效率为76%。
