Abstract
There is a demand for compact, low profile, and wideband antennas for modem wireless devices. The purpose of this dissertation is to develop two such antennas. A method of moments and finite difference time domain method are used for the design and analysis of the antennas. A new microstrip antenna is designed which has more than 90 % bandwidth. The operation of the antenna is explained and design equations are developed. The antenna is integrated with electromagnetic band gap structures (EBG) to examine if performance enhancement is possible. The simulation results are verified by limited measurements. A wideband loop antenna is also integrated with EBGs and significant perfbrrnance improvement is achieved.
