Abstract

A dual-band and dual-polarization antenna with independent frequency reconfigurable capacity is proposed. The antenna is composed of four radiation patches based on corrugated structure loaded with varactor diodes, where four radiation patches are arranged in orthogonal pairs to produce ±45° dual-polarization radiations. Due to the electronically controllable dispersion behaviors of the corrugated meta-structure, the low operating frequency can be arbitrarily controlled in the range from 3.48 to 3.72 GHz. In addition, short-circuit pins and another kind of varactor diodes are introduced in the radiation patches, which can create a high operating frequency ranging from 3.79 to 4.68 GHz without affecting the low resonant mode. Both simulated and measured results show well-controlled dual-band frequency independent reconfigurability of the proposed antenna, which exhibits good dual-polarization radiation and high isolation level. This frequency-reconfigurable dual-band antenna with stable dual-polarization characteristics may have potential applications in future smart wireless communication systems.

基于波纹元结构的频率可重构双频双极化天线

提出了一种具有独立频率可重构能力的双频双极化天线。该天线由四个基于瓦楞结构的辐射片组成，其中四个辐射片以正交对排列，产生±45°双极化辐射。由于波纹元结构的电子可控色散行为，低工作频率可以在3.48 ~ 3.72 GHz范围内任意控制。此外，在辐射贴片中引入了短路引脚和另一种变容二极管，可以在不影响低谐振模式的情况下产生3.79 ~ 4.68 GHz的高工作频率。仿真和实测结果表明，该天线具有良好的双频可重构性，具有良好的双极化辐射和高隔离度。这种频率可重构双频天线具有稳定的双极化特性，在未来的智能无线通信系统中具有潜在的应用前景。
