Excitation of multimode guide by stripline-fed slots
Abstract
The method of determination of impedance seen by stripline-exciting a multimode guide through a transverse slot in a ground plane is presented. An expression for the impedance is derived from complex power and discontinuity in modal voltage. Numerical results are presented for the slots symmetrically arranged parallel to the broad wall of a waveguide supporting TE(10), TE(20) and TE(30) modes.
