摘要

提出了一种简单的频率可重构电路(CDRA)，在接地面的h型槽中采用PIN二极管。相对介电常数为4.3的FR-4材料用于衬底和介电谐振器。DRA在5 GHz和10.3 GHz之间谐振，当PIN二极管关断和开时分别获得6.1 dBi和4.03 dBi增益。谐振频率5ghz处阻抗带宽为0.53 GHz，谐振频率10.3 GHz处阻抗带宽为1.75 GHz。天线在两个频率上的方向图都在偏侧。当二极管处于ON状态时，交叉极化电平为- 20.5 dBi，当二极管处于OFF状态时，交叉极化电平为- 16 dBi。提出的可重构CDRA可用于WLAN和x波段应用。

A Cylindrical Dielectric Resonator Antenna with Electronically-Switched Frequency for WLAN and X-Band Applications

A simple frequency re-configurable (CDRA) employing a PIN diode in the H-shaped slot of the ground plane is presented. FR-4 material with a relative permittivity of 4.3 is used for the substrate as well as the dielectric resonator. The DRA is resonating between 5 GHz and 10.3 GHz, achieving a gain of 6.1 dBi and 4.03 dBi when the PIN diode is turned OFF and ON respectively. The impedance bandwidth at the resonance frequency 5 GHz is 0.53 GHz and at 10.3 GHz is 1.75 GHz. The pattern of the antenna in both the frequency is in broadside. The cross-polarization levels are at −20.5 dBi for the ON state of the diode and −16 dBi for the OFF state respectively. The presented re-configurable CDRA can be used for WLAN and X-band applications.
