This study presents a novel four‐stage double‐layered waveguide bandpass filter and its simulation method. The longitudinal size of the waveguide filters is reduced by 50% due to the application of double‐layered structure. The four‐stage double‐layered bandpass filter with a 8.8 mm length, 6.2 mm width, and 1.6 mm height is manufactured by LTCC. It has a center frequency of 5.21 GHz, bandwidth of 300 MHz, pass‐band ripple of 0.1 dB, and insertion loss of 0.8 dB, which shows miniaturization, low insertion losses and meets the demand of next generation of WLAN system. © 2007 Wiley Periodicals, Inc.
