Abstract

This thesis deals with the design of a dual frequency tunable patch antenna operating at 900 MHz and 1800 MHz. The basic patch antenna is designed at approximately thrice the lowest operating frequency (900 MHz) and is tuned to the desired frequency by appropriate placement of shorting posts. The effect of the presence of a shorting post (not in use) on the resonant frequency of the antenna was studied. A novel technique is applied, using diodes, to make the patch switch between two operating frequencies. The tuning is verified through simulation and compared with the measured results on a fabricated antenna. The simulated radiation patterns at the two operating frequencies are presented.
