RM-CGHA28-15 Linear Polarization Corrugated Horn Antenna for 26.5–40 GHz Millimeter-Wave Applications

For engineers working with high-frequency RF and millimeter-wave systems, antenna performance is not only about gain. Beam control, polarization purity, impedance matching, and integration flexibility can be equally important. The RF MISO RM-CGHA28-15 Linear Polarization Corrugated Horn Antenna is designed to address these requirements across a broad 26.5–40 GHz frequency range, making it a practical solution for advanced measurement, communication, and radar applications.

With a 15 dBi typical gain and 1.2 typical VSWR, the RM-CGHA28-15 provides a strong combination of directional radiation and efficient RF matching. Its typical 3 dB beamwidth is 26° in the E-plane and 25° in the H-plane, helping create a well-controlled forward beam for applications where predictable radiation behavior matters. The antenna also specifies a minimum sidelobe level of 25 dB in the E-plane and 30 dB in the H-plane, together with 40 dB typical cross-polarization performance.

Simulation results further illustrate the antenna’s broadband behavior. Across the operating range, the simulated gain rises from approximately 15 dB at the lower end of the band to above 18 dB near 40 GHz, while the simulated VSWR remains low over most of the band. The simulated XPD performance also stays at a high level across the evaluated frequencies, supporting applications that benefit from good linear-polarization discrimination.

Integration flexibility is another key advantage. The RM-CGHA28-15 is available in two configurations: the C-Type uses a WR28 rectangular waveguide with UG-599/U flange, while the F-Type provides a 2.92 mm female coaxial interface. This allows engineers to select the version that better matches their existing test equipment or RF system architecture. Both versions use a gold-plated copper construction, while maintaining a compact and lightweight mechanical profile.

With 20 W CW and 40 W peak power handling, the RM-CGHA28-15 is well suited to a variety of high-frequency RF environments. According to the product specification, typical applications include 5G and millimeter-wave systems, radar systems, and satellite communications.

For laboratories, system integrators, and RF engineers seeking a compact 26.5–40 GHz corrugated horn antenna with controlled beam characteristics, multiple RF interface options, and strong polarization performance, the RM-CGHA28-15 offers a versatile platform for high-frequency testing and system integration.
