In this paper, a novel CPW-fed antenna is presented for UWB applications. The antenna mainly comprises of a simple circular patch and a modified ground plane. The inclusion of two novel symmetrical rectangular slots with inner area of 3×2.8 mm2 to the top corners of the antenna creates a new path for the current and consequently leads to the bandwidth enhancement. A rectangular stub is also adopted to further broaden the antenna impedance bandwidth. The proposed antenna has a compact size of 20×20×1.6 mm3 and covers the wide frequency band of 3-23.5 GHz (154%). Constant gain and suitable radiation patterns are observed for the presented antenna. Good agreement between the simulated and measured results clearly shows the validity of the proposed structure. The design steps and bandwidth enhancement process are discussed in detail.
