Abstract
An E-plane filter comprises a housing having a waveguide filter channel and a septum defining a plurality of couplers spaced apart along the length of the filter channel, thereby forming a resonator cavity between each adjacent coupler. The portion of the filter channel which accommodates the couplers and each resonator cavity is curved or otherwise changes direction in a plane transverse to the channel walls.
