Dual-mode Bandpass Filter Using Stub-Loaded Resonator
摘要
Abstract
High and low impedance microstrip lines of stepped impedance resonator are connected, and the input and output strong couplings need to reduce the coupling distance to square ring dual⁃mode resonator,but the circuit board production is difficult if the distance is too short.It is proposed that high and low impedance microstrip lines are connected vertically and the input and output are at the connection,so that the high and low impedance microstrip lines can couple with the square ring resonator,and the input and output can also be coupled.The coupling between stepped impedance resonator and square ring resonator and direct coupling between input and output both are enhanced. The simulation results show that the circuit size is reduced while the performance of filter is improved.关键词
