一种宽带圆极化缝隙天线的研究与设计
Research and Design of Broadband Circularly Polarized Slot Antenna
摘要
Abstract
A simple structure broadband circular polarization slot antenna is presented in this paper.It is composed of monolayer dielectric substrate and two metal layers and coveringWiMAX、WLAN and the 5G-sub6 GHz.Two rectangle patches and an inverted L strip are embedded at the corner of the square slot,then circularly polarized radiation is realized.The proposed antenna fed by the coupling microstrip.The bandwidth of the proposed antenna is extended by adjusting the length of the T-shaped microstrip and the width of the rectangular patch.The measured results show that the-10 dB impedance bandwidth is 1.91～7.14 GHz,the axial ratio bandwidth is 2.5～6.3 GHz,the relative ratio bandwidth is 86.4%,and the peak gain is 5.5 dBic at 5.5 GHz.关键词
