Abstract
A matching crossed slot has been analyzed by using a hybrid analysis of MoM/FEM. and the design procedure is presented. A good matching crossed slot has been designed at 11.85 GHz. The reflection is -16.7dB (radiated power is 97.9 %) and the axial ratio is 0.18 dB in the desired direction. To make the phase difference, the length of one slot is shorter than the resonant one while that of the other is longer.
