摘要
本文设计了一种宽带圆极化菱形印刷单极天线。菱形贴片由偏离中心的微带线馈电产生圆偏振(CP)。地平面配置为宽带操作进行了优化。同时满足10db回波损耗和3db轴比的带宽达到76% (1.92 ~ 4.27 GHz)。建议天线的尺寸为0.386 20 l (55?66 mm2),其中?0为自由空间波长,对应于带宽的中心频率。该天线的分数带宽尺寸比(BW/size)为1.97,高于文献中大多数CP单极天线。这种天线适用于Wi-Fi、WiMAX和其他性能优于圆极化的无线应用。
A rhomboid-shaped printed monopole antenna for wideband circular polarization
This paper presents the design of a wideband circularly-polarized printed monopole antenna with a rhomboid shape. The rhomboid-shaped patch is fed by a microstrip line offset from the center to generate circular polarization (CP). The ground plane configuration is optimized for wide bandwidth operation. Bandwidth (satisfying both 10-dB return loss and 3-dB axial ratio) of 76% (1.92 - 4.27 GHz) is achieved in this research. The size of the proposed antenna is 0.386 2 0 l (55?66 mm2) where ?0 is the free space wavelength which corresponds to the center frequency of the bandwidth. The antenna has a fractional bandwidth-size ratio (BW/size) of 1.97 which is higher than most CP monopole antennas in the literature. This antenna is suitable for Wi-Fi, WiMAX, and other wireless applications which outperform using circular polarization.
