Optimized waveguide E-plane metal insert filters for millimeter-wave applications
Abstract
A design theory is described for rectangular waveguide metal insert filters that includes both higher order mode interaction and finite thickness of the inserts. Optimized design data for three- to five-resonator type filters with several insert thicknesses suitable for metal stamping and etching techniques are given for midband frequencies of about 15, 33, 63, and 75 GHz. Measured passband insertion losses of prototypes for midband frequencies of 15, 33, and 76 GHz are 0.2, 0.6, and 0.7 dB, respectively.
