Waveguide Horn Antennas
Waveguide horn antennas are essential components in microwave communication systems, serving as interfaces that direct radio waves into or out of a waveguide. They are known for their high directionality and efficiency, making them ideal for applications ranging from satellite communications and radar to wireless networking. These antennas offer a broad bandwidth and stable performance, facilitating precise signal transmission and reception across various frequencies.

Interface and Construction
Define the Feed, Connector, Polarization and Mechanical Envelope
Electrical coverage alone is not sufficient for final selection. Mechanical interfaces and installation constraints should be reviewed at the same time as the RF requirements.
C
Coaxial Connector Options
Published options include N, TNC, 7-16, SMA, 2.92 mm, 2.4 mm and 3.5 mm connector families. State the required connector family and male or female interface.
W
Waveguide and Flange Interfaces
Waveguide-input configurations can be supplied with cover or grooved flange arrangements. Identify the required WRD family, flange designation and mating-interface standard.
P
Polarization
The brochure lists vertical and horizontal linear polarization entries and describes single- or dual-polarization options. Specify polarization orientation and port arrangement.
M
Material, Finish and Size
Published mechanical examples use aluminum with anticorrosion white paint. Example envelopes range from approximately 234 × 241 × 160 mm to 528 × 555 × 355 mm, depending on configuration.
Ordering Code
Part Number Interpretation
The brochure provides the following ordering example. Treat it as a model-code guide rather than a complete purchase specification.
Custom Requirements
Information to Include in the RFQ
A complete RFQ reduces model-selection errors and prevents electrical and mechanical assumptions from being carried into production.
Application Review
Typical RF and Microwave Uses
Suitability depends on the full antenna assembly, installation, operating band, interface and acceptance criteria. Published catalog values should be used for preliminary selection only.
Radar Systems
Directional transmission, reception, subsystem evaluation and antenna-pattern measurement.
Satellite Communications
Feed, ground-station, test-range and microwave-link configurations requiring broadband coverage.
EMC and RF Testing
Laboratory measurement setups, broadband illumination and calibrated test-system integration.
