摘要：
A new design of reduced-size, dual-frequency circular microstrip antenna is presented. The patch-size reduction is achieved by cutting four equally spaced slits at the boundary of the circular patch. The two operating frequencies can be controlled by selecting a suitable disk radios and adjusting the slit lengths. An approximate equation governing the frequency ratio of the two operating frequencies is also given. Details of the antenna design and experimental results are presented and discussed.
