Abstract
An antenna includes an antenna cavity structure that defines an antenna cavity and that has a cavity opening. The antenna also includes an antenna radiating element located within the cavity opening and operable to emit electromagnetic radiation that has a frequency and a wavelength and a radome structure covering the cavity opening. The radome structure includes a dielectric material and defines an antenna window that is transparent to the electromagnetic radiation. Due to the dielectric material of the radome structure, the antenna cavity has a depth less than one-fourth of the wavelength of the electromagnetic radiation and the cavity is filled with a low-dielectric material.
