摘要

现有的基于超表面的双频高增益天线存在不能灵活指定频率比和不能独立控制双频性能的共同限制。本文提出了一种解决这一问题的方法；它采用折叠反射天线和法布里-帕姆罗腔天线杂交的概念，用于高增益双波段操作。与之前的工作不同，这两个天线共享一个共同的孔径，但在结构上由极化选择表面分开，从而实现双频独立控制和灵活的频率比。为此研制了一种原型天线并进行了实验检验，测量结果与预期相符。

A Method to Realize the Dual-Band Antenna With Independent Control and Flexible Frequency Ratios Based on Metasurface

The existing dual-band high-gain antennas based on metasurface have a common limit that the frequency ratios cannot be flexibly designated while the dual-band performances cannot be controlled independently. Here, a method to solve this problem is proposed; it adopts the concept of hybridizing a folded reflectarray and a Fabry–Pérot cavity antenna for high-gain dual-band operations. Different from previous works, the two antennas share a common aperture but are separated structurally by a polarization-selective surface that enables dual-band independent control and flexible frequency ratios. A prototype antenna is thus developed and experimentally examined, and the measured results agree well with expectations.

期刊介绍： IEEE Antennas and Wireless Propagation Letters (AWP Letters) is devoted to the rapid electronic publication of short manuscripts in the technical areas of Antennas and Wireless Propagation. These are areas of competence for the IEEE Antennas and Propagation Society (AP-S). AWPL aims to be one of the "fastest" journals among IEEE publications. This means that for papers that are eventually accepted, it is intended that an author may expect his or her paper to appear in IEEE Xplore, on average, around two months after submission.
