Abstract

In this article, a dual-port ceramic-based radiator is discussed and examined. A pentagon-shaped slot is used to excite the cylindrical-shaped dielectric, which stimulates HEM11δ mode in it. A meta-surface is placed over the dual-port radiator for transforming linear waves into circularly polarized (CP) waves from 5.51 to 6.01 GHz. LHCP antenna gain is also increased from 6.0 to 9.0 dBi within the working frequency range, after applying the proposed meta-surface. Experimental verification of antenna prototype confirms the working band of the proposed radiator from 5.25 to 6.17 GHz. The isolation between the ports is more than 20 dB, which is in the acceptable limit. The better value of far-field and diversity factors confirms the suitability of the proposed antenna in wireless LAN (5.5 GHz) applications.

线性到圆形极化波转换器加载双端口介质谐振器天线与增强增益的WLAN应用

本文对一种双端口陶瓷散热器进行了讨论和研究。利用五角形槽激发圆柱形介质，激发介质中的HEM11δ模态。在双端口散热器上放置一个元表面，用于将5.51至6.01 GHz的线性波转换为圆极化(CP)波。应用元曲面后，LHCP天线在工作频率范围内的增益也从6.0 dBi提高到9.0 dBi。天线样机的实验验证证实了所提出的辐射器的工作频段为5.25 ~ 6.17 GHz。端口间隔离大于20db，在可接受范围内。较好的远场和分集系数值证实了该天线在无线局域网(5.5 GHz)应用中的适用性。
