Abstract

The main objective of this research work is to design a multiband reconfigurable patch antenna for millimeter wave applications. In this paper, a slotted circular patch antenna is designed on Polymide substrate material with dielectric constant 3.5. To reconfigure patch antenna, two MEMS switches are placed within slots inside the patch and are investigated under four different conditions by alternatively turning ON/OFF MEMS switches. The different performance parameters such as return loss, gain and Voltage Standing Wave Ratio (VSWR) are measured and it is found that the proposed antenna is efficiently resonating on three frequency bands by tuning the switches with effective gain and VSWR. The proposed reconfigurable antenna is resonating on important frequencies such as 30GHz, 35GHz, 45GHz and 60GHz with effective gain and VSWR without changing the dimension of patch antenna. This antenna can be used for millimeter waves based high speed short range wireless communications, sensing and security applications.

毫米波应用的多波段可重构贴片天线

本研究工作的主要目标是设计一种适用于毫米波应用的多波段可重构贴片天线。本文在介电常数为3.5的聚酰胺衬底材料上设计了一种开槽圆形贴片天线。为了重新配置贴片天线，在贴片内部的插槽中放置两个MEMS开关，并通过交替打开/关闭MEMS开关来研究四种不同条件下的情况。测量了天线的回波损耗、增益和驻波电压比等性能参数，通过调整开关的有效增益和驻波电压比，发现天线在三个频段上都能实现有效的谐振。该可重构天线在不改变贴片天线尺寸的情况下，在30GHz、35GHz、45GHz和60GHz等重要频率上具有有效增益和驻波比。该天线可用于基于毫米波的高速短距离无线通信、传感和安全应用。
