摘要

在本文中，我们提出了一种新颖的矩形微带槽天线，具有频率可重构特性，用于无线应用。在两个开关的帮助下，实现了天线的可重构特性，从而使其能够在多种模式下工作。通过打开和关闭这些开关，天线的工作频率可以改变。当两个开关都处于ON状态时，天线具有单个2.4GHz (WLAN)频段，回波损耗带宽为−10dB，范围为2.3GHz ~ 2.5GHz。天线具有2.4GHz、5.2GHz (WLAN)和7.8GHz (ITU)三频段，−10dB回波损耗带宽分别为2.3GHz-2.6GHz、5.1GHz-5.3GHz和7.7GHz-7.9GHz。当其中一个开关处于ON状态时，天线具有双重工作模式。该天线的驻波比< 2，在设计频段增益良好。模拟结果与实测结果非常吻合。

A novel frequency reconfigurable rectangular step slotted antenna for WLAN/ITU

In this article, we have proposed a novel rectangular microstrip slot antenna with frequency reconfigurable characteristics for wireless applications. With the aid of two switches the reconfigurable characteristic of antenna is achieved thus enabling it to work in multiple modes. By making these switches ON and OFF, the antenna's frequency of operation can be varied. The antenna has a single band at 2.4GHz (WLAN) with a −10dB return loss bandwidth ranging from 2.3GHz to 2.5GHz when both the switches are ON. Antenna has triple bands at 2.4GHz, 5.2GHz (WLAN) and 7.8GHz (ITU) with −10dB return loss bandwidths ranging from 2.3GHz–2.6GHz, 5.1GHz–5.3GHz and 7.7GHz–7.9GHz respectively when both the switches are OFF. Antenna has dual mode of operations when either of the switch is ON. The proposed antenna has VSWR < 2 and good gain for designed bands. Both the simulated and measured results are in close agreement.
