## Abstract The improvement of spurious responses of a λ/4 resonator bandpass filter (BPF) using a microstrip line (MSL) is carried out. Firstly, a basic mechanism for improving the resonance responses of the λ/4 resonator, under the condition that the excitation method is changed, is presented. Se
