Horn Antennas

A horn antenna, also known as a microwave horn, is a type of antenna that is made of a flaring metal waveguide that is shaped like a horn. Through the emission of radio waves in a beam, horn antennas are able to boost the control of the direction of emissions. Horn antennas usually operate at microwave and ultra-high frequencies over 300 MHz. Besides a better degree if directivity of emissions, they also allow for a broad bandwidth and a lower standing wave ratio. To perform radiated immunity EMC testing, a horn antenna can be used to radiate RF in an anechoic chamber.

Double ridge guide horn antennas are considered the best choice when broadband coverage is required, as these antennas can cover a frequency range of 170 MHz to 40GHz. These also allow for full band coverage of the MIL-STD-461 standard.

Standard gain horn antennas (pyramidal horns) are precise by providing a high gain and power output with a frequency range between 750 MHz to 40 GHz. Engineers can use smaller power amplifiers when testing with standard gain horn antennas.

Avalon Test Equipment carries a variety of horn antennas from top manufacturers (Com-Power, Amplifier Research, A.H. Systems, and more) to meet your testing requirements. Rent or purchase from Avalon and Test With Confidence®.
