Using characteristic mode analysis (CMA), two orthogonal modes ... The size of a single antenna element and the 1 $\times $ 2 array-unit (AU) are 20 $\times $ 21.5 mm2 and 40 $\times $ 21.5 mm2, ...

In AMI, each array element’s response is orthogonally modulated and aggregated, and the aggregate is squared using a noncoherent power detector. The resulting low-frequency cross-correlations are ...
