Sectoral Waveguide Horn Antennas

ATM manufactures a wide array of microwave sectoral horn antenna in both E and H plane configurations for rectangular waveguide.  

In certain instances the use of the sectoral horn antenna is an effective method of achieving broadband ’broadcast’ type coverage required in base station transmission systems.  Other uses include narrow field identification required in traffic control systems.

Both E plane sectoral horn antenna and H plane sectoral horn antenna configurations are useable for either vertical or horizontally polarized applications and provide the maximum beam width in the un-flared dimension.

Units we offer are true sectoral horn antenna parallel side designs.  Only one waveguide dimension is flared with the other sides of the sectoral horn antenna remaining parallel.  This makes for the large fan type coverage in the un-flared plane and a considerably narrower beam in the other plane.

Please call us with your specifications to discuss your sectoral horn antenna requirements with one of our RF design engineers.
