What is standard gain horn antenna？
Jun 24, 2023
Product Description
The standard horn antenna can be divided into three types: waveguide input, coaxial input and waveguide coaxial combined input. Working frequency range: 1.72 ~ 40 GHz; Waveguide size from WR430 to WR28;; 3dB beam width: 10018 30 550; The most common gain values are 10, 15, 20 and 25dB;; Optional interface: standard IEC and EIA flange interface or coaxial N-Type,SMA,2.92 interface. Precision machining can ensure accurate and lasting performance. The basic materials are aluminum (6061), brass, oxygen-free hard copper or copper alloy, and the surface treatment includes silver plating, gold plating, shackles plating, passivation, conductive oxidation and other treatment methods. The external dimension, flange, material, surface treatment and electrical indicator requirements of the antenna can be customized according to the user's requirements.
design Principle
The design of a standard gain horn antenna follows certain principles to achieve a constant gain over a wide frequency range. The horn antenna consists of a flared metallic structure shaped like a horn, with a gradually expanding aperture. The key design parameters include the length, flare angle, and aperture size, which are determined based on the desired operating frequency and bandwidth. The transition region between the feed source and the horn section is carefully designed to ensure efficient power transfer.

feature
- Constant Gain: The primary advantage of an SGHA is its constant gain over a specified frequency range. This characteristic makes it suitable for applications that require a uniform radiation pattern and consistent performance across the operating frequencies.
- Wide Bandwidth: Standard gain horn antennas can cover a wide frequency range, typically from a few hundred megahertz to several gigahertz, depending on the design parameters. This versatility allows for flexibility in various applications, where multiple frequency bands need to be supported.
- Directional Radiation Pattern: SGHAs exhibit a directional radiation pattern, which means they focus their beam in a particular direction. This characteristic aids in achieving long-range communication, high-gain transmission, and accurate signal reception.
- Low sidelobe levels: Sidelobes refer to the radiation energy in undesirable directions. SGHAs are engineered to minimize sidelobe levels, which reduces interference from unwanted signals and enhances the antenna's overall performance.
Application
Radar Systems: Standard gain horn antennas find extensive use in radar systems, both in direct radiating applications and as feed horns for parabolic reflector antennas.
Satellite Communication: SGHAs play a vital role in satellite communication systems for transmitting and receiving signals.
Wireless Networking: such as point-to-point microwave links and Wi-Fi systems, standard gain horn antennas are used for their directional characteristics.
Measurement Instruments: SGHAs are commonly utilized in measurement instruments, such as spectrum analyzers and antenna test ranges.
