A compact Multiple Input Multiple Output (MIMO) antenna of size 41 × 30 × 0.8 mm 3 is proposed in this paper for Ultra-Wideband (UWB) application with high isolation. The proposed UWB-MIMO antenna consists of two SemiCircle Antennas (SCA) which acts as a radiating patch for achieving UWB operation. The frequency range of UWB is from 3.04 to 10.87 GHz. The high isolation is achieved by inserting an E-shaped slot in the radiating patch, and further enhancement is achieved by inserting a narrow slot in the ground plane. The proposed antenna is simulated using CADFEKO tool. The antenna is fabricated and tested for its performance using Network Synthesizer. It is observed from the results that the antenna is suitable for UWB applications.
