Design of Dual Frequency Microstrip Square patch antenna

Abstract

Dual frequency microstrip patch antennas is important when two operating frequencies are far apart to avoid the use of separate antenna. In addition, dual frequency microstrip patch antennas also can provide large bandwidth in application in which large bandwidth is really need when operating at two separate transmit-receive bands. In this paper, the design, simulation, fabrication and measurement of dual frequency microstrip square patch antenna is presented.
