摘要
本文提出了一种新颖的带开槽贴片的可重构微带天线设计。提出了一种基于FR-4基片的双工作频率孔径耦合微带天线结构的设计方案。引入了两种槽型(水平槽型和垂直槽型)，并在水平槽中集成了三个理想的交换机，实现了频率的可重构性。利用CST Microwave Studio Suite 2009在2-6GHz工作频率下对该设计进行了仿真。研究了两种不同槽位和开关配置对系统性能的影响，并从x轴间距、槽位长度、回波损耗和增益等方面对结果进行了分析和讨论。仿真结果表明，该天线能够在2.36 GHz和5.67GHz双工作频率下工作。
A reconfigurable microstrip antenna with a slotted patch at dual frequency
This paper presents a novel design of a reconfigurable microstrip antenna with a slotted patch. The proposed design was based on the structure of an aperture coupled microstrip antenna using FR-4 substrate at dual operating frequency. Two types of slot (horizontal and vertical) were introduced and three ideal switches were integrated into the horizontal slot to achieve frequency reconfigurability. The design was simulated using CST Microwave Studio Suite 2009 at operating frequency of 2–6GHz. The effects of two different slots and switch configurations were studied and the results were analyzed and discussed in terms of x-axis spacing, slot length, return loss and gain. The simulation results were presented and the proposed antenna is able to operate at dual operating frequency of 2.36 GHz and 5.67GHz.
