The design and implementation of a Coplanar Waveguide (CPW) band rejection filter with modified signal line is presented in this paper. In particular, the modification is created as a spiral etched in the signal line which perturbs the surface current on the line, providing additional capacitance and inductance that reflects as the band stop characteristics in the frequency spectrum. A filter prototype has been designed fabricated, numerically and experimentally assessed. The obtained results, as well as the agreement between numerical and experimental are quite good.

Abstract
The design and implementation of a Coplanar Waveguide (CPW) band rejection filter with modified signal line is presented in this paper. In particular, the modification is created as a spiral etched in the signal line which perturbs the surface current on the line, providing additional capacitance and inductance that reflects as the band stop characteristics in the frequency spectrum. A filter prototype has been designed fabricated, numerically and experimentally assessed. The obtained results, as well as the agreement between numerical and experimental are quite good.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione
