WR18 Combined Input Modular Horn Antenna

WR18 Combined Input Modular Standard Gain Horn Antenna for mmWave Metrology

This product is a thoughtful example of a Standard Gain Horn Antenna, featuring a combined waveguide and coaxial input design. The model is built around a WR18 (BJ500) waveguide size and comes with a 1.85-K type connector. It is made from copper and aluminum materials for good durability. As a Combined Input Horn, this antenna offers users more than one way to feed the signal. This flexibility comes from its split body construction. Unlike one piece designs, this unit can be taken apart into two main sections. This makes it easier to transport and maintain. Users can also swap out the waveguide to coaxial converter module or the horn section based on the frequency band or test accuracy needed. This modular approach gives engineers more control over their test setup without needing to buy multiple complete antennas.

This horn antenna operates in the millimeter wave range from 40GHz to 60GHz. The Voltage Standing Wave Ratio (VSWR) is rated at 1.6, which shows solid impedance matching at these high frequencies. The antenna delivers a stable 15dB gain, providing reliable directional radiation for demanding test tasks. The 1.85-K connector is a precision type made for millimeter wave work. 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 real 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 with both. The simple but smart construction keeps the overall cost reasonable while adding real value through flexibility.

One clear strength of this Combined Input Horn is its modular design in metrology and test environments. When testing different frequency bands or needing different levels of accuracy, users do not have to swap out the whole antenna. They just change the relevant module. This saves money and reduces downtime. 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 labs that share equipment across different sites or for calibration services that travel to customers.

In practical use, this Standard Gain Horn Antenna handles professional millimeter wave tasks very well. For calibration labs, it serves as a standard source antenna for gain measurements and system validation at high frequencies. Its 15dB gain and low VSWR help produce clean and trustworthy results in the 40-60GHz band. In the communication field, it supports millimeter wave signal transmission and reception for emerging technology validation and link testing. The copper and aluminum build gives the antenna good strength while keeping it suitable for precision work. The combined input setup allows quick compatibility with different feed test equipment, which is a big help when moving between different test benches or customer sites. It stands as a good example of how a well designed Combined Input Horn can meet the demands of modern millimeter wave engineering through smart modular construction.
