The new product line has five categories:
- Standard gain horn antennas for frequencies up to 220 GHZ
- Conical gain horn antennas for frequencies up to 220 GHZ
- Omni-directional antennas for frequencies up to 99 GHZ
- Horn lens antennas for frequencies up to 99 GHZ
- Wide-angle scalar feed horn antennas for frequencies up to 99 GHZ
The waveguide sizes of these antennas range from WR5 to WR19, with gains of 3.5 dBi to 25 dBi nominal. Each represents a solution for point-to-point and/or point-to-multi-point applications.
Standard Gain Horn Antennas
Standard gain horn antennas are used in a wide variety of applications due to their high power handling capability, low loss, high directivity, and near-constant electrical performance across a broad bandwidth.

A member of this group, the FMWAN1032 has a gain of 25 dBi and is suited for frequencies ranging from 140 GHZ to 220 GHZ. It has a waveguide size of WR-5 and a UG-387/U-Mod Round Cover Flange.
Conical Gain Horn Antennas
These antennas share many characteristics with standard gain horn antennas.

The FMWAN1068 WR-5 waveguide conical gain horn antenna offers low gain variation across its operating frequency range and 11 degrees of half power beam width.
Fairview Microwave’s omnidirectional antennas offer operating frequencies from 58-99 GHz and can be used in a wide variety of applications. They offer low gain variation across their operating frequency. Members of this group all have horizontal and vertical beam widths of 360° and 45°, respectively.
