In modern wireless communication, MIMO technology is a key breakthrough reshaping antenna design. This book, based on rigorous research, helps readers grasp MIMO's performance edges, innovative antennas, and experimental results. We compared MIMO and SISO architectures; experiments proved MIMO's quantified advantages. We developed an inset feed dual-polarised patch antenna (with advanced combining) that outperforms vertical polarised systems. Its DGS-integrated feed line boosts inter-port isolation by nearly 30 dB, reducing interference. Top electromagnetic software simulated...
