摘要

本研究提出了一种使用阻抗面作为地平面的宽带开放谐振器天线(ORA)的理论实现。阻抗表面的实现是基于贝塞尔滤波器的设计方法。本文将表明，所提出的方法提供了一种不使用复杂结构来设计ORA的替代方法。我们提出的ORA设计显示了3dB增益带宽的显著改善- 24.7% -峰值增益为16.9 dBi。给出了仿真结果，并与离散金属和平坦地面的ORA设计进行了比较。

Wideband High-Gain Open Resonator Antenna Using a Flat Impedance Surface

This research presents a theoretical implementation of a wideband open resonator antenna (ORA) using an impedance surface acting as a ground plane. The impedance surface realization is based on the Bessel filter design methodology. It will be shown that the proposed methodology provides an alternative approach to design ORA without using complicated structures. Our proposed ORA design shows significant improvement in the 3dB gain bandwidth - 24.7 % - with a peak gain of 16.9 dBi. Simulated results are shown and compared with the ORA design with discretized metallic and flat ground.
