WR18 Combined Input High Gain Horn Antenna

WR18 Combined Input 25dB Gain Modular Horn Antenna for Precision mmWave Metrology

This product is a high performance example of a Standard Gain Horn Antenna, built with a combined waveguide and coaxial input design. The model is based on a WR18 (BJ500) waveguide size and comes with a precision 2.4-K type connector. It is constructed from copper and aluminum materials for strength and durability. As a Combined Input Horn, this antenna gives users flexible feeding options through its split body construction. Unlike solid one piece designs, this unit can be taken apart into two main sections. This makes transport and maintenance much easier. Users can swap out the waveguide to coaxial converter module or the horn section based on the frequency band or test accuracy needed. This modular approach allows engineers to adapt their test setup without buying multiple complete antennas. The higher 25dB gain sets this model apart for applications that need stronger directional radiation.

This horn antenna operates in the millimeter wave range from 39.2GHz to 59.6GHz. The Voltage Standing Wave Ratio (VSWR) is rated at 1.6, which shows solid impedance matching across this wide high frequency band. The antenna delivers a strong and stable 25dB gain, providing excellent directional radiation for demanding measurement tasks. The 2.4-K connector is a precision type specifically made for millimeter wave work at these frequencies. The combined input design means users can feed the antenna through either the waveguide port or the coaxial port using the adapter module. This is a major advantage when working with different types of test equipment. Some labs may have older gear with coaxial outputs while newer setups use waveguide. This antenna works well with both. The straightforward but smart construction keeps the overall cost reasonable while adding real value through flexibility and high gain performance.

One clear strength of this Combined Input Horn is its modular design for precision metrology and test environments. When testing different frequency bands or needing different levels of accuracy, users do not have to replace the whole antenna. They just change the relevant module. This saves money and cuts down on setup time. The antenna is widely used for signal transmission and reception in the microwave and millimeter wave bands. Its main application areas include metrology, testing, and communication. For engineers working on system calibration, antenna pattern measurements, or component characterization at millimeter wave frequencies, this unit provides a stable and repeatable reference. The split body design also makes the antenna easier to pack and ship, which matters for calibration services that travel to customer sites or for labs that share equipment across different locations. The higher 25dB gain gives users more signal strength for challenging measurement scenarios.

In practical use, this Standard Gain Horn Antenna handles professional millimeter wave tasks very effectively. For calibration labs, it serves as a standard source antenna for gain measurements and system validation at high frequencies. Its 25dB gain and low 1.6 VSWR help produce clean and trustworthy results in the 39.2-59.6GHz band. In the communication field, it supports millimeter wave signal transmission and reception for advanced technology validation and link testing. The copper and aluminum build gives the antenna good structural strength while keeping it suitable for precision work. The combined input setup allows quick compatibility with different feed test equipment, which is a real help when moving between different test benches or working with mixed equipment inventories. It stands as a solid example of how a well designed Combined Input Horn with high gain and modular construction can meet the tough demands of modern millimeter wave engineering.
