A Compact Orthogonal Dual Element MIMO Antenna for K, Ka-Band and mmWave Applications

This paper introduces a novel design and optimization approach for a compact K-band Multiple Input Multiple Output (MIMO) antenna, catering to the requirements of high-speed wireless communication systems. It addresses challenges like compactness, high gain, and mutual coupling effects in MIMO setups by utilizing advanced simulation techniques and optimization algorithms. Through analyzing frequency needs and radiation characteristics, it explores various antenna configurations and feed network architectures. The focus is on achieving compactness, efficient power distribution, and impedance matching while evaluating metrics like radiation pattern, impedance bandwidth, envelope correlation coefficient (ECC), and diversity gain. The resulting design is optimized for integration into diverse high-speed wireless communication systems like 5G networks, satellite communication, radar systems, and wireless backhaul links, offering valuable insights for researchers and engineers in the field.
