Abstract

Microstrip Antennas have many advantages such as low profile, light weight, can be easily matched with microwave integrated circuits which leads to use this type of antennas in different applications, on the other side, the great disadvantage of these antennas is the narrow bandwidth which is 2 to 5 %. In this paper a single element circular Microstrip antenna has been designed which had a narrow bandwidth and then two methods of bandwidth enhancement had been designed and compared to the single patch, these two techniques gave a bandwidth of 10% and 38 % respectively. The three designs had been simulated using Microwave Office Package.
