In this paper, the authors present the design aspects and radiation performance of a compact broadband single-feed circular patch antenna with key shaped slot for modern wireless communication systems. The two measured resonant frequencies of proposed antenna lie in the lower and upper bands adopted by IEEE 802.16 for Wi-Max communication systems. This dual band operation is achieved by introducing an offset circular ring slot near the periphery of conventional circular patch while broadband performance from proposed structure is achieved by attaching a narrow slit with this ring slot.
