提出了一种新型的矩形两层叠置宽带介质谐振器天线。DRA由介电谐振器（DR）和位于地平面上方的薄介电段组成，并由连接到同轴探头的小金属贴片激发。与以前的设计不同，在一个或多个高介电常数的薄段上具有较低介电常数的DRA，该天线的顶部DR具有比较低段更高的介电常数。理论和实验结果表明，所提出的DRA可以实现非常宽的带宽。©2006 Wiley期刊公司微波光学学报，48 (2):1630-1633,2006；在线发表于Wiley InterScience （www.interscience.wiley.com）。DOI 10.1002 / mop.21716
A novel two‐layer stacked wideband dielectric resonator antenna (DRA) of rectangular shape is proposed. The DRA is composed of a dielectric resonator (DR) and a thin dielectric segment, which reside above a ground plane, and is excited by a small metallic patch connected to a coaxial probe. Unlike its previous designs that have a DRA of a lower permittivity above one or more thin segments of higher permittivity, the top DR in this antenna has a higher permittivity than the lower segment. Theoretical and experimental results show that the proposed DRA can achieve a very wide bandwidth. © 2006 Wiley Periodicals, Inc.
