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, ...

Abstract: Imaging a fast maneuvering target has been an active research area in past decades. Usually, an array antenna with multiple elements is implemented to avoid the motion compensations involved ...
