Small circular microstrip antenna with dual-frequency operation
TLDR
In this article, a dual-frequency operation of the circular microstrip antenna is demonstrated, which can result in a much reduced antenna size and provide a tunable frequency ratio of ~2.55 − 3.83 for the two operating frequencies.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.read more
