Abstract :
The theoretical design principles of new compact resonators are presented. The coupling coefficients between resonators was investigated and their dependence on the coupling gaps is discussed. Two-pole and four-pole preselector filters, for GSM900, have been designed and manufactured. The filter responses demonstrate the feasibility of selective filters developed with the proposed miniature resonators.
