In this paper, we have proposed a semi-circular patch antenna with a slot in the patch and a ground plane with a notch. The proposed antenna is designed using FR-4 substrate with a dielectric constant of 4.4 and the height of the substrate is 1.6mm. We simulated the antenna using HFSS and obtained the S11 < -10dB in the range of 3GHz to 15GHz, which covers the UWB range of 3.1GHz to 10.6GHz. An active circuit is designed and simulated using ADS to improve the gain of the antenna when working in a lossy medium other than air.

A new small circular patch antenna for ultra-wideband (UWB) applications is presented. By studying this structure, it is shown that the insertion of a slot with the desired length and width in the ground plane, can lead to a large bandwidth. Our antenna, whose dimensions are 18×12×1.58 mm3, was fed by an SMA female connector with characteristic impedance of 50Ω in order to measure the return loss and VSWR and to compare them with the simulation results. The bandwidth obtained from measurements ranges from 3.52 to 13.67 GHz for VSWR < 2 and from 3.26 GHzto14.23GHz for VSWR < 3. The radiation pattern is omnidirectional on most of the operating band. High Frequency Structure Simulator (HFSS) was used for simulation whose results are in good agreement with the measured parameters.
