In this paper we propose a new type of comb-line filter which consists of a couple of meander-shaped quarter-wavelength microstrip resonators. We investigate the filtering characteristics through FD-TD simulations. Furthermore, we design the filter and discuss its filtering characteristics through experiments as well as numerical simulations. It is found that this filter realizes a considerable reduction in the size of structure and sharp bandpass characteristics with multiple attenuation poles around the passband.
