摘要: Tri-band bandpass filter using single open or short stub loaded resonators is presented in this paper. The second and the third resonant frequencies of resonator can be flexibly controlled by tuning length impedance stub, whereas first frequency fixed. Two microstrip filters were designed simulated, proving concept an excellent way. prototype tri-band achieved insertion loss 1.3, 1.7 1.5 dB at 2.4, 3.5, 5.8 GHz, 0.8 1.3 1.57, 2.45, 5.2 respectively.
