A Quad-port MIMO Antenna with Beam Switching and Pattern Reconfiguration Capability for UWB Applications

A quad port antenna configuration with four antipodal vivaldi radiating elements is presented in this paper. The proposed Multiple Input Multiple Output (MIMO) antenna consists of multiple switches and no parasitic elements like directors or reflectors, to exhibit beam switching and pattern reconfiguration. The absence of these elements reduces the design complexity. The radiation of the proposed antenna can be switched along +y, -x, -y and +x directions, if the antenna is placed in xy- plane. The proposed antenna operates over Ultra Wide Band (UWB) band of 3.1GHz to 10.6GHz making it as a promising choice for futuristic applications like Internet of Things (IoT).
