Applying Characteristic Mode Analysis to Systematically Design of 5G Logarithmic Spiral MIMO Patch Antenna

The Theory of Characteristic Modes (TCM) provides a natural and systematic approach for designing Multiple-Input Multiple-Output (MIMO) antennas with high efficiency and uncorrelated antenna patterns. Recent progress in the growing field of MIMO antenna design, supported by TCM, is examined in this...
