ABSTRACT This article examines the triple-band rectangular dielectric resonator antenna (RDRA) excited with novel composite feeding structure (combination of inverted H-shaped monopole and vertical strip). Three attractive features of proposed design are as follows: (i) composite feeding structure creates dual higher order modes in RDRA (i.e., and ); (ii) triple-band characteristic is achieved with the help of hybrid antenna concept; and (iii) adjacent bands with higher order modes have been merged to enhance the bandwidth. Simulated outcomes have been practically confirmed with the help of developed prototype of proposed antenna. The proposed RDRA is operated over three frequency bands, i.e., 1.45–1.63 GHz, 3.62–4.1 GHz, and 4.55–5.86 GHz. The proposed design is quite suitable for WLAN (5.2/5.8 GHz), WiMAX (5.5 GHz), AMSAT (5.6 GHz), GPS (1.57–1.58 GHz), point-to-point microwave, and telemetry in the USA (4.44–4.99 GHz).

用于多频段应用的混合矩形介质谐振器天线

摘要 本文研究了用新型复合馈电结构（倒 H 形单极子和垂直条带的组合）激励的三频矩形介质谐振器天线 (RDRA)。所提出的设计的三个吸引人的特点如下：(i) 复合馈电结构在 RDRA 中创建双高阶模式（即 和 ）；(ii) 借助混合天线概念实现三频特性；(iii) 具有更高阶模式的相邻频段已合并以提高带宽。模拟结果已在拟议天线的开发原型的帮助下得到实际证实。提议的 RDRA 在三个频段上运行，即 1.45-1.63 GHz、3.62-4.1 GHz 和 4.55-5.86 GHz。所提议的设计非常适用于 WLAN (5.2/5.8 GHz)、WiMAX (5.5 GHz)、AMSAT (5.6 GHz)、GPS (1.57–1.
