Abstract

An extension of the principles of multimode phased array waveguide simulators to triangular spaced array antennas is presented. It is also shown how such a simulator can be used for any polarization of excitation, if the radiating elements are circular symmetric. Contour plots of the reflection and the transmission coefficients are shown for circular polarization of excitation. The radiating elements are open-ended circular waveguides in a triangular lattice. A comparison between the simulator technique and the small test array technique to approximate the infinite array performance is also given.
