1. A high power antenna comprising:
- a conical horn for receiving an electromagnetic input signal and radiating an output signal in response thereto said conical horn having an waveguide input, an output aperture, and a gradual taper from said waveguide input to said aperture, said taper being tangential to said waveguide input on one end and tangential to said output aperture on the other end thereof;
an inner window disposed within said conical horn; and
an outer window mounted at the aperture of said conical horn.

Abstract
A high power TM01 mode radio frequency antenna. The inventive antenna comprises a conical horn for receiving an electromagnetic input signal and radiating an output signal in response thereto. An inner window is disposed within the conical horn. An outer window is mounted at an output aperture of the conical horn in alignment with the inner window. The antenna has a gradual taper from a waveguide input to the aperture over a cone angle of 45 degrees. The outer window is mounted at the aperture in concentric alignment with the inner window. For an optimal compact design, the inner and outer windows are of polycarbonate construction.
