Compact and high-performance band stop filter on textile substrate

A band stop filter developed on a denim textile substrate is presented. The filter geometry is composed of interconnected half-wavelength parallel coupled resonators, in a novel microstrip filter configuration. Simulated results were obtained through the wave concept iterative method and Ansoft Designer software, for comparison purposes. In addition, prototypes were fabricated and measured for validating the simulation results. Good agreement is reported between simulated and measured results
