摘要

本文提出了一种适用于各种无线应用的三频低剖面圆极化（CP）六边形介质谐振器天线（HDRA）阵列。为了提高HDRA的性能，设计了一种使用简单微带功率分配器的四元线性阵列。该HDRA以1.52GHz的第一谐振频率激励TEd01模式。所提出的设计工作在三个频段，即1.44-1.61 GHz、2.95-3.27 GHz和4.00-4.84 GHz，分数带宽分别为10.98%、11.02%和22.20%。它还提供了良好的增益和超过70%的辐射效率，在所有谐振点具有更好的辐射模式。此外，它在3.12GHz和4.25GHz附近分别具有50MHz和650MHz的CP带宽。所提出的HDRA阵列适用于不同的无线应用，如GPS（1-2 GHz）、WiMAX（2-4 GHz）和WLAN（4-8 GHz）。

A Low-profile 4-element Circularly Polarized Hexagonal DRA Array for Triple-band Wireless Applications

This paper presents a triple-band low-profile circularly polarized (CP) hexagonal dielectric resonator antenna (HDRA) array for various wireless applications. A 4-element linear array is designed using a simple microstrip power divider to improve the performance of the HDRA. This HDRA excites TEd01 mode at a first resonant frequency of 1.52 GHz. The proposed design operates in three frequency bands, i.e. 1.44 - 1.61 GHz, 2.95 - 3.27 GHz, and 4.00 - 4.84 GHz with the fractional bandwidth of 10.98%,11.02% and 22.20%, respectively. It also provides good gain and more than 70% of radiation efficiency with a better radiation pattern at all the resonating points. Further, it has a CP bandwidth of 50 MHz and 650 MHz around 3.12 GHz and 4.25 GHz, respectively. The proposed HDRA array is suitable for different wireless applications such as GPS (1 - 2 GHz), WiMAX (2 - 4 GHz), and WLAN (4 - 8 GHz).
