Abstract :
A multiport circuit level model is developed for an open-cavity, quasioptical power combiner. The model is developed using Hermite-Gaussian beam model theory, the Lorentz reciprocity theorem, and the determination of diffraction losses. Measurements were made using an electrically short inverted L antenna. One-port and two-port measurements were made for specified modes for the q=35 family and found to compare very well with simulated results.<>
