【Abstract】 In the paper, the equivalcnt circuit method is cmployed in analyzing the Tee junction with a narrow slot coupling. Aller using variational method, the main parameters in the network are derived. By using those mathematical expressions, an algorithm is built up, and then the CAD analysis values for S parameters corresponding the H plane Tee junction are obtained. Through the comparison between our results and experiment measurement as well as other numcrical data, it is shown that the analysis is effcctive and correcl and the program is valid. It is also demonstrated that the CAD program could be applied in the practical antenna design.更多还原
