A novel cram of reconfigurable patch antenna using RF MEMS

Abstract

Over the past three decades, Micro-Electro-Mechanical Systems (MEMS) have provided advancements in different fields of electronics. MEMS technology also enabled microwave and antenna engineers to produce some existing and novel radio-frequency components resulting as a new research field, namely RF MEMS. The use of MEMS technology for RF and microwave applications promises to solve many limitations, RF MEMS can reduce manufacturing cost, size, weight, and improve performance and battery life. In terms of performance, MEMS can provide low-loss switching and tuning of microwave circuits with higher dynamic range, lour cost, and greater flexibility than the competing techniques. In this paper we proposed a reconfigurable patch Antenna structures using MEMS switches. This concept leads to reduction in space and multiple functionality from a single antenna structure.
