Abstract :
A 3rd order novel compact E-plane ridge waveguide filter is presented. Miniaturization of 2:1 is achieved upon introducing a configuration of parallel coupled E-plane ridge waveguide resonators. The presented filter allows for a transmission zero at finite frequencies to address sharp cutoff specifications. Furthermore it maintains the fabrication simplicity and mass-producibility of standard E-plane filters. Numerical and experimental results are presented to validate the presented configuration.
