Characteristics of a 240 to 400 MHz 4-inch depth ridges-cavity cross-slot antenna on a curved ground plane
Abstract
A cross-slot antenna backed by a 33-in. square x 4.18-in. deep ridged cavity is described for operation in the 240 to 400 MHz band. The antenna was developed for a potential flight test evaluation using a satellite-to-aircraft communication link. Measured VSWR, radiation patterns and gain with the antenna mounted on a 9.5 ft x 9.5 ft cylindrically curved ground plane are shown. This curved ground plane simulates a section of the fuselage of a KC-135 aircraft.
