18-40GHz Broadband Horn Antenna

Broadband Horn Antenna 18-40GHz

This product is a professional Broadband Horn Antenna designed for K and Ka band millimeter wave applications requiring high gain and cost effectiveness. The antenna operates from 18GHz to 40GHz and is built from aluminum for light weight and good durability. As a Broadband Horn, it features a simple yet rugged all metal construction that provides excellent mechanical strength. The electrical performance sits between standard pyramidal horns and ultra wideband double ridged horns. Compared to ridged horn antennas, this model has a simpler structure and lower cost, giving it a clear price advantage. The antenna offers linear polarization and can be mounted in either horizontal or vertical orientation. This flexibility makes installation easy and allows users to switch polarization without needing different antennas. The high 19dB gain sets this model apart for millimeter wave applications that need strong directional radiation across a wide frequency range.

This broadband horn antenna delivers solid electrical performance across its operating range from 18GHz to 40GHz. The Voltage Standing Wave Ratio (VSWR) is rated at 2.0, which shows good impedance matching for such a wide bandwidth at millimeter wave frequencies. The gain is 19dB or higher, providing strong signal strength for demanding test and measurement tasks. The radiation pattern is symmetrical, and the amplitude phase characteristics are favorable for accurate measurements. The antenna offers high radiation efficiency, which means most of the input power gets radiated rather than lost as heat. The all metal construction ensures long term reliability even with frequent handling. The design also provides good shielding against outside interference. The simple structure keeps the cost reasonable while delivering professional grade performance for measurement tasks across K and Ka bands.

One clear strength of this Wideband Test Antenna is its excellent balance between high gain, wide bandwidth at millimeter wave frequencies, and low cost. It is widely used for EMC electromagnetic compatibility chamber testing up to 40GHz, where consistent performance across the 18-40GHz range is essential. The antenna is also suitable for antenna near field and far field measurements at millimeter wave bands, serving as either a transmitting or receiving element. In microwave and millimeter wave research, it helps with development and calibration tasks. For electromagnetic interference troubleshooting and radiation monitoring at high frequencies, this antenna provides reliable detection across the 18-40GHz band. The antenna also supports next generation wireless communication and 5G 6G network testing, defense and military applications, radar and satellite systems operating at K and Ka bands, as well as teaching and research in university labs. The simpler construction compared to ridged horns makes this antenna a practical choice for facilities that need high performance at millimeter wave frequencies without paying for ultra wideband capabilities they do not require.

In practical use, this EMC Horn handles professional millimeter wave test tasks very well. For EMC chambers, it serves as a reliable antenna for both radiated emission and radiated immunity testing in the K and Ka bands. The ability to mount it horizontally or vertically gives users flexibility to meet different test standards. For antenna measurement ranges, the symmetrical pattern and stable gain help produce accurate and repeatable results at millimeter wave frequencies. The aluminum construction keeps the antenna light enough for easy mounting on precision positioners and stands. The low VSWR of 2.0 ensures good impedance matching and minimal signal reflection at high frequencies. The 19dB minimum gain provides excellent signal to noise ratio for most millimeter wave measurement setups, especially those requiring long cable runs or measuring low power signals. It stands as a solid example of how a well designed Broadband Horn can meet the demanding needs of EMC testing, antenna measurement, and communication system validation in the K and Ka bands while offering excellent value for money.
