Abstract
AbstractWe consider a novel surface mount ceramic filter for wireless communication systems. The high permittivity ceramic filling of the basic triple‐mode waveguide cavity makes proposed bandpass filters physically small. Integrated microstrip to ceramic waveguide transitions provide effective connection of the filter into a planar circuit. The theory is based on the singular integral equation method in conjunction with generalized scattering matrix technique. The principal feature of the simulation algorithm consists of utilization of weighted Gegenbauer polynomials as the basis functions for the Galerkin's procedure. A design example is shown for L‐band filter. © 2002 Wiley Periodicals, Inc. Microwave Opt Technol Lett 33: 373–377, 2002; Published online in Wiley InterScience (www.interscience.wiley.com).
