Microstrip antennas are also known as printed antennas and they have a variety of applications in radar systems, microwave communication links, satellite communication systems, wireless and mobile communication systems, medical equipment, etc. In this paper, a model of inverted T-shaped slot rectangular patch antenna is designed and simulated to evaluate the performance. The proposed antenna is...

A frequency agile triple band microstrip antenna using defected ground structure for WLAN/WiMAX application is presented, in which frequency agility is electronically achieved by changing the bias voltage of varactor diode. A defected ground structure rectangular patch with dual inverted L-shaped fed with a cross shaped strip line is used to achieve multiple bands. Simulated results are validat...

This paper describes the effect of inserting a rectangular shape defected ground structure (DGS) into the ground plane of the conventional rectangular microstrip patch antenna (CRMPA). The performances of the CRMPA are characterized by varying the dimensions of the rectangular slot (RS-DGS) and also by locating the RS-DGS at specific position. Simulation results have verified that the CRMPA inc...
