Abstract
A microstrip lowpass filter with enhanced performance is developed. The studied filter is based on a novel patch resonator that features strong slow-wave effects, and can also implement either an improved roll-off or an enhanced stop-band. A demonstrator filter with 3dB cutoff frequency f c=2.4GHz is optimally designed, fabricated and measured. Results indicate that a roll-off of 92.5dB/GHz together with a relative stop-band bandwidth of 135.5 (referred to a 30dB suppression) is obtained while achieving a highest figure-of-merit of 10106. Both simulations and measurements are presented and compared. © The Institution of Engineering and Technology 2009.
