Multiple frequency antenna feed system |
| 摘要 |
An multi-frequency antenna feed system has a corrugated conical horn and a diplexer interconnected serially to be operative in two frequency bands represented by frequencies fH and fL corresponding to wavelengths lambda H and lambda L respectively, where 2fL</=fH. Corrugated grooves on the inner surface of the conical horn have the depth h, where lambda L/4<h< lambda L/2. The corrugated conical horn has the inside diameter at its reduced diameter end which is not less than 2.6 lambda o, where lambda o designates a wavelength at which the depth of the corrugated grooves ranges from three quarters of the wavelength and one complete wavelength.
