ABSTRACT:
A dual frequency antenna and radome system, including a dual frequency antenna system for operation at a first, higher frequency band and at a second lower frequency band. The antenna system includes a first antenna operable at the first frequency band and a second antenna operable at the second frequency band. The first and second antenna systems are orthogonally polarized. A radome is tuned for dual frequency operation, and includes a dielectric wall having a thickness equal to one-half wavelength at a frequency in the first frequency band. The radome further includes a grid of monopole elements formed on a surface of the dielectric wall orthogonal to the first antenna to tune the radome to efficient operation at the second frequency band.
