Popis: In this article, a filter size reduction of 46% is achieved by reducing a substrate-integrated waveguide (SIW)-loaded evanescent-mode bandpass filter to a half-mode SIW (HMSIW) structure. SIW and HMSIW filters with 1.7 GHz center frequency and 0.2 GHz bandwidth were designed and implemented. Simulation and measurements of the proposed filters utilizing combline resonators have served to prove the underlying principles. SIW and HMSIW filter cavity areas are 11.4 and 6.2 cm2, respectively. © 2012 Wiley Periodicals, Inc. Int J RF and Microwave CAE, 2013.
