Standard horn antennas can be classified into three types: waveguide - type input, coaxial - type input, and waveguide - coaxial combined input.
The operating frequency range is 1.72 - 40 GHz; the waveguide sizes range from WR430 to WR28; the 3 - dB beamwidths are 10°, 18°, 30°, and 55°; the most common gain values are 10 dB, 15 dB, 20 dB, and 25 dB; the available interfaces include standard IEC and EIA flange interfaces, or coaxial N - Type, SMA, and 2.92 interfaces.
Precision machining ensures accurate and long - lasting performance. Basic materials include aluminum (6061), brass, oxygen - free hard copper, or copper alloy structures. Surface treatment methods include silver - plating, gold - plating, nickel - plating, passivation, and conductive oxidation. The external dimensions, flanges, materials, surface treatment, and electrical specifications of horn antennas can all be customized according to user requirements.
