Design and analysis of miniaturized multifunction two elements microstrip array antenna with SPDT switch for communication and radar applications

Abstract

Modern satellite, wireless communications, and radar systems often demand the wideband performance for multi-channel and multi-function operation. Recent technologies enable electronic and RF circuits in radar and communication devices to be miniaturized and become physically smaller in size. Antenna design has been one of the key limiting constraints to the development of small communication terminals, next generation wireless communication and radar requirements of multi-band and multi-function operation. In this paper, design of miniaturized multifunction two elements microstrip array with single-pole double-throw (SPDT) transmitter/receiver (T/R) switch has been introduced and investigated. The entire proposed array antenna has been evaluated using a commercial software. The final proposed design has been fabricated and the radiation characteristics have been illustrated using network analyzer to meet the requirements for multifunction applications.
