Abstract

This paper presents a frequency reconfigurable dual-pole, dual-band waveguide bandpass filter. Varactor diode and chip capacitor loaded planar split ring resonators are used on the transverse plane of a waveguide to form the filter. Numerical simulations are carried out using CST microwave studio (version 14). Measured result shows tuning range of the bands are 8.12-8.58 GHz and 10.22-10.68 GHz, respectively. The measured result shows good agreement with the simulated one. The total length of the proposed filter is 10 mm.
