Abstract

ABSTRACT In order to improve the performance of 5 G Millimeter wave, a new gap-coupled fed ultra-wideband circularly polarized antenna is proposed. Firstly, by fabricating the top structure of the slot antenna ，a C-shaped patch structure can adjust the surface transverse current as well as the longitudinal current to generate circularly polarized waves; then the feed structure at the bottom layer of the antenna is designed and resonance is generated with the top layer of the antenna to expand bandwidth. From the simulation and the measurement results can know that the −10 dB impedance bandwidth of the antenna is 19.21 GHz−45.50 GHz (81.25%); the 3 dB circularly polarized axial ratio (AR) bandwidth is 20.59 GHz−38.33 GHz (60.2%), with ultra-broadband circular polarization performance. The designed antenna has a simple structure, small size, low profile and wide working bandwidth, which can fully include N257, N258 and N261 bands, and has a good application prospect in 5 G communication.

基于相邻耦合馈电的超宽带圆极化毫米波天线

摘要为了提高5g毫米波的性能，提出了一种新的间隙耦合馈电超宽带圆极化天线。首先，通过制作缝隙天线的顶部结构，c形贴片结构可以调节表面横向电流和纵向电流，从而产生圆极化波;然后设计天线底层馈电结构，与天线顶层产生共振，扩大带宽。从仿真和测量结果可以知道，天线的−10 dB阻抗带宽为19.21 GHz−45.50 GHz (81.25%);3db圆极化轴比(AR)带宽为20.59 GHz ~ 38.33 GHz(60.2%)，具有超宽带圆极化性能。所设计的天线结构简单、体积小、外形低、工作带宽宽，可以全面覆盖N257、N258和N261频段，在5g通信中具有良好的应用前景。
