Abstract
In this paper, a Multiple Input Multiple Output (2x2MIMO) patch antenna for multiband applications has been proposed. It has been designed using groups of rings nearby the stepped cut at four corners of the patch and a separation in mid slot. This modification is proposed in order to increase the resonant frequencies and reduce the mutual coupling. The proposed 2x2 MIMO patch antenna is simulated using Computer Simulation Technology (CST), fabricated and tested. With such small geometrical dimensions, the proposed antenna is suitable for LTE (1.8 GHz), WiFi (2.4 GHz), and WiMax (3.5 GHz, 5.2 GHz and 5.5 GHz) applications
Highlights
Multiple Input Multiple Output (MIMO) antennas are operating with multiple number of transmitters and receivers that are used to provide the high data rate required for services
This is because the previous key technology such as Single Input Single Output (SISO) antenna encountered drawbacks such as multipath fading and low data rate capacity
MIMO antenna’s designs face challenges like the mutual coupling, which exists due to electromagnetic interaction between antenna elements, and affects antenna efficiency
Summary
Multiple Input Multiple Output (MIMO) antennas are operating with multiple number of transmitters and receivers that are used to provide the high data rate required for services. A 2x2 MIMO patch antenna has been proposed for multiband applications with groups of rings with the stepped cut at four corners and a mid slot separation, in order to increase resonant frequencies and decrease the mutual coupling.
