Abstract

A microstrip transmission line of half wavelength loaded with a radial stub operates as a dual mode resonator. By controlling the dimensions of the radial stub it is possible to control the nature of coupling between two modes. By controlling the coupling between the resonator and source/load, it is possible to realize transmission zero with a single dual mode resonator. It is also possible to locate the transmission zero either above or below the pass band region by appropriately changing the nature of different couplings. A dual mode resonator filter with controllable transmission zero is proposed which demonstrates asymmetric filter characteristics.
