36 to 40GHz Prime Focus Parabolic Antenna

Prime Focus Parabolic Antenna 36-40GHz for Ka Band Satellite and Radar

This product is a professional Parabolic Antenna with a prime focus front feed design. The antenna operates from 36GHz to 40GHz in the Ka band and features a compact reflector with dimensions of φ302*183mm. As a Prime Focus Parabolic Antenna, the feed is positioned at the focal point in front of the parabolic reflector. This design provides high gain, strong directivity, long distance transmission, very narrow beamwidth, and excellent focusing ability at millimeter wave frequencies. The antenna offers single linear polarization. The structure is simple, making installation and alignment easy. The antenna features a BJ320 waveguide interface for low loss high frequency operation.

This prime focus parabolic antenna delivers excellent electrical performance across its operating range from 36GHz to 40GHz. The Voltage Standing Wave Ratio (VSWR) is rated at 2.0, which shows good impedance matching at Ka band frequencies. The gain is 37dB or higher, providing very strong signal strength for demanding millimeter wave communication and radar tasks. The E plane and H plane beamwidth is 2 degrees plus or minus 0.3 degrees, giving extremely narrow focused beams for precise targeting. The single linear polarization is suitable for many Ka band radar and communication systems. The compact size makes this antenna practical for space constrained installations.

One clear strength of this Prime Focus Parabolic Antenna is its very high gain and extremely narrow beamwidth at Ka band frequencies. It is widely used in satellite communication earth stations, broadcast television and radio, microwave long distance point to point links, weather remote sensing, aerospace telemetry tracking and control, defense and military systems, field industrial and emergency communication, as well as educational and scientific research. The 37dB gain allows this antenna to work effectively over very long distances at millimeter wave frequencies. The extremely narrow beamwidth provides very precise pointing and excellent rejection of off axis interference.

In practical use, this Prime Focus Parabolic Antenna handles professional Ka band communication and radar tasks very well. For satellite earth stations, it serves as a high performance terminal antenna for Ka band uplink and downlink. For radar systems, the high gain and very narrow beam provide accurate target detection and tracking at millimeter wave frequencies. For communication links, the antenna delivers strong signals over long distances. The BJ320 waveguide interface provides low loss signal transmission at Ka band. The compact 302mm size makes installation practical for many sites. It stands as a solid example of a well designed prime focus parabolic antenna for Ka band applications from 36GHz to 40GHz.
