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: A 8×8 narrow wall planar slotted array antenna by using differential feed with enhanced gain and reduced cross polarization radiation at X band has been proposed. A H-plane tee is designed ...
