The horn antenna is a broadband passive device, shaped like a pyramid horn, referred to as a TEM antenna, which guides the beam of radio waves at a precise frequency. FT-RF Double Ridged Horn antennas have frequency capabilities ranging from 400MHz to 40GHz depending on type and style. These series are characterized by a huge frequency range and extremely high input powers. With increasing frequency, the gain rises to a maximum of 18 dBi. At higher frequencies, the increased gain compensates for the increasing cable losses.

The advantages of Horn antenna:

- Wide bandwidth: Because the horn antenna has no resonant parts, it can function over a wide range of frequencies.

- Easy waveguide interface: These antennas are very easy to interface to waveguide due to their shape, but they can also be designed with a transition so that a regular coaxial feeder can be used.

- Easy to make, simple design.

The horn is suitable for both transmitting and receiving purposes, especially suitable for EMC and immunity test measurements.

Recommended Accessories

- SMA Cable: High-quality special SMA cable
