研究了一种平面馈电的三频双极化全向介质谐振器天线。通过使用具有两组馈电电路的新型馈电网络来获得垂直和水平极化。前者的极化是通过使用一个圆形贴片与八个短路短截线，每个短截线有一个V形的开路短截线，而后者是通过使用两个集成的回路。为了进行演示，三频双极化双工器设计在2.4 GHz、5.2 GHz和5.8 GHz频段，用于Wi-Fi应用，极化隔离度分别为16 dB、25 dB和23 dB。天线原型的直径和高度分别仅为0.640\lambda_{0}$和0.162\lambda_{0}$，其中$\lambda _{0}$是真空中的最低工作波长。设计中采用了介质谐振器TM模、介质谐振器TE模、介质谐振器加载平面谐振模和环形模，本文将给出详细的设计过程。
A tri-band dual-polarized omnidirectional dielectric resonator antenna (DRA) with a planar feed is investigated. Both vertical and horizontal polarizations are obtained by using a novel feed network that has two sets of feeding circuits. The former polarization is obtained by using a circular patch with eight shorted stubs, each having a V-shaped open stub, whereas the latter is obtained by using two integrated loops. For demonstration, the tri-band dual-polarized DRA is designed in 2.4-, 5.2-, and 5.8-GHz bands for Wi-Fi applications, with polarization isolations of 16, 25, and 23 dB, respectively. The diameter and height of the antenna prototype are only $0.640\lambda _{0}$ and $0.162\lambda _{0}$ , respectively, where $\lambda _{0}$ is the lowest operating wavelength in vacuum. Dielectric resonator (DR) TM modes, DR TE modes, a DR-loaded planar monopole mode, and a loop mode are used in the design, and the details will be given in this article.
