Multilayer bandpass filter in dual-band applications / Farhanna Razali

A multilayer filter technique is proposed to enhance an existing design of a dual-mode dual-band bandpass filter topology. In this paper the design adapts vias to connect two quarter-wavelength parallel coupled-lines to two half-wavelength lines creating a dual-path structure. The influence of diffe...
