A COMPACT 2 × 2 UWB-MIMO ANTENNA WITH FUNNEL SHAPED STUB FOR ISOLATION ENHANCEMENT

Abstract

The growth of wireless communication technologies demands advancement in designing antennas. The essential need for efficient and low-profile antennas are required for wireless communication. The development of antenna structures(compact) with performances is considerably enhanced over traditional antenna structures and methodologies. A compact printed and planar multiple-input multiple-output (MIMO) for ultra wideband (UWB) communications is presented. Two circular disc monopole antenna elements constitute the proposed UWB-MIMO antenna, operating over the frequency band of 4-10 GHz. The required antenna performance in terms of frequency response, gain, S-parameters, and voltage standing wave ratio (VSWR) can be achieved in the range of 3-7 GHz gain with minimum attenuation. The proposed antenna is simulated using computer simulation technology (CST) microwave studio software, and the designed antenna will operate for wireless communication application.
