Excitation of waveguide by stripline- and microstrip-line-fed slots
Abstract
An analysis is presented of the excitation of a waveguide by stripline- and microstrip-line-fed slots in the transverse cross section of the waveguide. The field distribution required for the analysis of both stripline-fed and microstrip-fed slots is determined from one common general formulation; the impedance loading on the stripline/microstrip line is determined from the complex power flowing down the waveguide and discontinuity in modal voltage of stripline or microstrip line. Numerical results are presented on the normalized resistance and reactance, and the effect of a reactive stub in the feedline terminating the slot is examined. The design curves on slot length vs frequency are presented for different values of dielectric constants.
