提出了一种采用阶梯阻抗发夹型谐振器的紧凑型低通滤波器。为了实现宽阻带抑制，引入了径向短截线。对这种新型低通滤波器进行了理论分析、仿真和制作。实测结果与电磁仿真结果吻合较好，电路仅占用0.08λg×0.08λg。
A compact lowpass filter using a stepped impedance hairpin resonator is presented. To achieve wide stopband rejection, radial stubs were introduced. The new lowpass filter has been analysed, simulated and fabricated. Measured results are in good agreement with the electromagnetic simulation, and the circuit only occupies 0.08λg×0.08λg.
