MISCELLANEOUS REFLECTOR ANTENNAS

Seavey Engineering designs and manufactures specialized reflector antennas for demanding customer applications. Any type of reflector, beam shape or special characteristic can be provided for frequencies up to 40 GHz.

We maintain extensive modeling software for analysis and synthesis of all types of reflector antennas. We can simulate reflector shape, surface and alignment tolerance errors, feed and feed blockage characteristics and nearby metal objects such as plates, solids, and wires. This capability permits us to commit to a design early in the project. Correlation of these modeling programs with experimental data is excellent. Some interesting special designs are noted below.
