✦ Synopsis


A new design of reduced-size, dual-frequency circular microstrip antenna is presented. The patch-size reduction is achie¨ed 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 radius and adjusting the slit lengths. An approximate equation go¨erning the frequency ratio of the two operating frequencies is also gi¨en. Details of the antenna design and experimental results are presented and discussed.

This paper presents a new, compact, dual-frequency design of single-feed circular microstrip antennas with an offset circular slot placed close to the patch boundary. It is found that, when the radius of the offset slot is about 0.38᎐0.62 times the radius of the circular patch, dual-frequency operat
