In this paper, a compact microstrip reconfigurable bandpass filter (BPF) covering the 3.4 to 3.8 GHz spectrum bandwidth for 5G wireless communications is proposed. The planar filter uses three ring resonators with 50 Ω transmission line impedances for input and output terminals. The coupling between the resonators is adjusted to resonate at the centre frequency with third-order bandpass Butterworth properties. Varactor diode and biasing circuit are modeled to tune the resonant frequency in the desirable band. The presented tunable filter is designed on Rogers RO3010 substrate with a relative dielectric constant of 10.2 and a compact size of 17×5×1.27 mm3. The proposed filter is simulated and optimized using CST microwave studio software.
