Spurline structures and its application on microwave coupled line filter
We propose and demonstrate experimentally that spurline structures enhance the rejection bandwidth of microwave bandstop coupled line filters. We have investigated the influence of spurlines structures on the rejection bandwidth of a typical microwave coupled line filters (with a notch frequency at 3.0 GHz). Momentum simulations and experimental results show that using spurline structures (designed to present a notch frequency at 2.4 GHz and 3.2 GHz) enhance in high percentage the performance of microwave coupled line filters (CLF).
