Horn antennas, also known as microwave horns, are antennas modified by a waveguide and flared metal horn in a conical, square, or rectangular shape. Because the horn apparatus allows the antenna to emit radio waves as a beam, increasing the directivity of the emissions, they are used for radiated immunity EMC testing.
A horn antenna commonly operates at microwave and ultra-high frequencies exceeding 300 MHz, offering a degree of directivity, a broad bandwidth, and a low standing wave ratio (VSWR). ATEC offers horn antenna rentals for a variety of frequency ranges, from leading manufacturers such as
A.H. Systems,
Amplifier Research,
ETS-Lindgren, and more.
