摘要：

This letter presents a new design of a probe-fed circular microstrip antenna with two open-ring slots for broadband operation. Due to the two embedded open-ring slots in the circular patch, two resonant modes of similar radiation characteristics are found to be excited at frequencies in the vicinity of the fundamental resonant frequency (f(11)) of a corresponding simple circular microstrip antenna without slots. The two closely excited resonant modes can cause the enhancement of the impedance bandwidth of the proposed circular microstrip antenna, and experimental results show that the obtained bandwidth for the proposed antenna can be greater than two times that of a simple circular microstrip antenna. The proposed antenna design and obtained broadband performance are presented. (C) 1999 John Wiley & Sons, Inc.
