Multiple Input Multiple Output (MIMO) is a technology that uses multiple antennas at both transmitter and receiver to enhance channel capacity without sacrificing spectrum or power. This technology increases the signal-to-noise ratio and error rate, creating a more stable connection and less congestion. Previous MIMO antenna designs for UWB, X-, and Ku bands have been reported in various studies. However, these designs lack beam forming, good isolation, compact size, use of power dividers, and switches. Beamforming improves spectral efficiency by providing a better signal-to-noise ratio (sNR). To achieve desired beam forming, different measurement setups involving power dividers and switches will be connected to ports of the tentatively designed antennas. Difficulties in characterizing MIMO antennas include multi-port, large size, high cost, high mutual coupling, and difficulty feeding multiple ports. The proposed work addresses these issues by designing reconfigurable MIMO antennas using a PIN or varactor diode. some previously introduced reconfigurable MIMO antennas are narrow bands, large in size, and have low isolation. The main objective of this work is to design MIMO antennas and investigate measurement techniques for Multi-ring MIMO antennas. The significance of this work lies in various wireless communication applications such as Ultra-Wideband communication, satellite communication, and Imaging Radar Applications. The proposed work aims to address these issues and develop more effective MIMO antenna designs for various wireless communication applications.
