Abstract :
By using a single shorting pin and a single probe feed, the dual-frequency operation of the circular microstrip antenna is demonstrated. This dual-frequency design can result in a much reduced antenna size and provide a tunable frequency ratio of ~2.55-3.83 for the two operating frequencies. Typical experimental results are presented
