摘要

提出了一种用于GPS/GLONASS的圆极化cpw馈电方形缝隙天线，该天线具有嵌入希尔伯特曲线和矩形贴片。该天线由两条希尔伯特曲线、三个矩形贴片和CPW的增强馈电带构成。通过调整相关参数，可以得到1.575 GHz的GPS频段和1.609 GHz的GLONASS频段。测量到的- 10db回波损耗阻抗带宽为480mhz(30.48%)，范围为1.35 ~ 1.83 GHz。在1.55 ~ 1.71 GHz范围内测量到的3db轴比带宽为160 MHz(9.8%)。天线在1.575 GHz时的增益为3.98 dBic，在1.609 GHz时的增益为3.46 dBic。

A circularly polarized CPW-fed square slot antenna with embedded Hilbert-curves and rectangular patches for GPS/GLONASS operations

This paper presents a circularly polarized CPW-fed square slot antenna with embedded Hilbert-curves and rectangular patches for GPS/GLONASS operations. The proposed antenna is constructed with two Hilbert-curves lines, three rectangular patches and the enhanced feed strip of CPW. By way of adjusting the relevant parameters, we can obtain the GPS band at 1.575 GHz and GLONASS band at 1.609 GHz. The measured -10 dB return loss impedance bandwidth are 480 MHz (30.48%) from 1.35 to 1.83 GHz. The measured 3 dB axial ratio bandwidth is 160 MHz (9.8%) from 1.55 to 1.71 GHz. The polarization of radiation patterns are RHCP and the antenna gain are 3.98 dBic at 1.575 GHz, 3.46 dBic at 1.609 GHz, respectively.
