Evaluation of the ETS-Lindgren Open Boundary Quad-Ridged Horn 3164-06

The ETS-Lindgren quad-ridged, open boundary horn, model 3164-06, was modeled using FEKO computational software. Its gains were measured in the US Army Research Laboratory ARL building 504 anechoic chamber and its patterns and S11 parameters were measured in building 203 tapered chamber to characterize its electrical properties. These models and measurements were compared with each other and with the characterization given by its manufacturer, ETS-Lindgren. Results from simplified FEKO computer models of the antenna and measurements performed at ARL largely agreed with the ETS-Lindgren characterization given by a typical 3164-06 antenna in its manual. Strong oscillations in the frequency spectrum for the S11 and therefore the voltage standing wave ratio VSWR in the ARL measurements may be an exception, though more such measurements are needed.
