Tuneable and Dual-Band Circular Microstrip Antenna with Stubs

K. P. Ray, Member, IEEE and Girish Kumar Senior Member, IEEE

Page 1036.

Abstract:

A circular microstrip antenna loaded along its feed axis with either one stub or two stubs has been analyzed using improved linear transmission line model. When the length of the stub is small, the frequency is tuned over 9% range in L-band and, when it is comparable to /4, it exhibits dual-frequency operation. The experimental results are in good agreement with the theoretical results.
