Horn Antenna Applications

29/03/2022 Posted by: ft-rf.com.tw

Horn antennas are very popular from 200 MHz frequency to higher frequencies up to 40GHz. The horn antenna has a distinctive design that is enlarged towards the end.

Horn antennas typically feature a directional radiation pattern with a high antenna gain of 10-20 dBi, some antennas have a higher gain such as the standard horn antenna up to 25 dBi. Horn antennas feature a low VSWR and a wide impedance bandwidth.

As the frequency of operation is increased, the gain of horn antennas increases. This is because the horn aperture is always measured in wavelengths; the horn antenna is "electrically larger" at higher frequencies because a higher frequency has a smaller wavelength.

The advantages of FT-RF Horn antenna:

  • Moderate directivity, low standing wave ratio (SWR), broad bandwidth
  • Easy waveguide interface: These antennas are very easy to interface to the waveguide due to their shape, but they can also be designed with a transition so that a regular coaxial feeder can be used.
  • Simple construction and adjustment
  • ODM OEM OBM & RD services.

Horn antennas are easy to make and put together. Each type of antenna has a wide range of applications:

Broadband Horn Antenna:

  • Antenna Measurement
  • EMC/ RF Measurement
  • Surveillance System
  • Radar Detection System

Quad-ridged Horn Antenna:

  • Antenna Measurement
  • Electromagnetic Measurement
  • Electromagnetic Compatibility Testing (EMC test)
  • Ultra-wideband Radar Detection

Double-Ridged Horn antenna:

  • Antenna measurement
  • Communication systems
  • Satellite tracking systems
  • Electromagnetic Compatibility Testing (EMC test)

Standard Gain Horn Antenna:

  • Antenna measurement
  • Radar Detection System
  • Wireless Communication
  • Spectrum Monitoring
  • Electromagnetic interference Testing (EMI test)
