Abstract :
A compact tri band bandpass filter (BPF) using a combination of half wavelength tri-section and dual section stepped impedance resonators is presented, which has a triple pass band at 2.45 GHz, 3.5 GHz and 5.5 GHz respectively. The passband bandwidth is suitable for WiMAX and WLAN application. Insertion loss within each of the bands is less than 2 dB. The overall filter dimension is 38 by 36.5 mm.
