%X On account of narrow bandwidth, many applications of microstrip antennas are limited in great degree. How to widen its bandwidth is being concerned by lots of scholars at home and abroad. In this paper, resonant frequency of the deformed circular microstrip antennas is investigated based on variational principle and the perturbation concept. The theoretical results are found to be in reasonable agreement with the experimental ones for small modified element. This paper provides a theoretical and experimental bases for the synthesis of microstrip antennas.
