SYNTHESIS AND REALIZATIONS OF A NEW CLASS OF DUAL-MODE MICROWAVE RECTANGULAR FILTERS
We give rectangular realizations of new structures able to improve quasi-elliptic functions. These rectangular realizations overcome the difficulties of electromagnetic analysis of circular structures. We describe first the design procedure of this new type. Then we present two sets of experimental results to illustrate the accuracy between theory and performance. This new configuration can create zeros at right or left hand of the band. With a very powerful computational electromagnetic analysis, the design needs less tuning. To validate this new concept of filtering, we present the measurements of two TE10 / TE30 rectangular dual-mode filters.
