Teberio et al., "Design Procedure for New Compact Waffle-Iron Filters With Transmission Zeros," in IEEE Transactions on Microwave Theory and Techniques, vol. 66, no. 12, pp. 5614-5624, Dec. 2018. doi: 10.1109/TMTT.2018.28781980018-948010.1109/TMTT.2018.2878198https://academica-e.unavarra.es/handle/2454/33439In this paper, a novel waffle-iron filter with transmission zeros at multiple frequencies, along with its design procedure, is presented. The proposed filter features a high-power behavior and a wide rejected band in a single compact structure by means of a set of transmission zeros that can also be placed close to the passband. Its design method rests on a divide-and-rule strategy, where the physical dimensions of the constituent design entities (DEs) can be easily computed in a very short time. A novel high-power compact waffle-iron filter with transmission zeros at multiple frequencies has been designed as well as several classical waffle-iron filters with transmission zeros at one frequency only, using a detailed step-by-step procedure which avoids the bruteforce optimizations needed until now. Multipactor and corona simulations have been conducted proving a high-power handling capability of 1.8 kW and 78.6 W, respectively. A prototype of the novel filter has been fabricated, obtaining a remarkable accordance between the simulated and measured results.application/pdfeng© 2018 IEEE.
