Abstract
A tri-band bandpass filter using λ/4 parallel-coupled stepped impedance microstrip is proposed. The center frequencies of the three passbands are located at 1.78 GHz, 3.9 GHz, and 5.94 GHz respectively. A transmission zero is generated to improve the isolation between the first and second passbands. The experimental results agree well with the simulated ones. The circuit size is measured to be 0.04 λg × 0.75 λg.
