Dual-band and shorted microstrip patch antenna design for communication system applications

Abstract

Dual-band and miniaturized microstrip patch antennas are in much demand due to their small size, light weight and planar configuration. In this thesis, an attempt is made to design and analyze miniaturized microstrip patch antennas, patch arrays and dual-band microstrip patch antennas. These antennas can be used in any application, over a wide frequency range of 1 GHz to 10 GHz. An array of shorted microstrip patches has been designed to operate at the desired frequency. The dual-band operation is obtained by either creating a notch on one of the radiating patch of the microstrip patch antenna or loading the radiating patch by a slot. The patch used for this dual-band operation is shorted using a shorting wall. The results of both the designs are analyzed. The study carried on, helps to find the various antenna parameters and the optimized design of an antenna array and dual-band antenna.
