18-40GHz Double Ridged Horn Antenna

 Double Ridged Horn Antenna 18-40GHz

This product is a high performance Ultra Wideband Double Ridged Horn Antenna designed for millimeter wave applications requiring broad frequency coverage and stable performance. The antenna operates from 18GHz to 40GHz, covering the K and Ka bands, and is built from a combination of aluminum and copper materials. The copper provides excellent conductivity while the aluminum keeps the overall weight manageable. As a Double Ridged Horn, it features a rugged all metal construction that provides exceptional mechanical strength. 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 wide frequency coverage from 18GHz to 40GHz means one antenna can handle tasks that would otherwise require multiple narrowband units. This band covers important millimeter wave frequencies used in satellite communication, radar, and advanced test applications.

This double ridged horn antenna delivers excellent electrical performance across its operating range. The Voltage Standing Wave Ratio (VSWR) is rated at 2.0, which shows very good impedance matching for an ultra wideband design covering multiple frequency decades. The gain is 13.5dB or higher, providing strong signal strength for demanding test and measurement tasks at millimeter wave frequencies. 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 using both copper and aluminum ensures long term reliability even with frequent handling. The design also provides excellent shielding against outside interference. The cost effectiveness of this antenna makes it accessible for labs, universities, and test facilities with various budget levels while delivering professional grade performance.

One clear strength of this Wideband Test Antenna is its versatility across many application areas at millimeter wave frequencies. It is widely used for EMC electromagnetic compatibility chamber testing, where consistent performance across a broad frequency range is essential. The antenna is also suitable for antenna near field and far field measurements, 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 multiple bands. The antenna also supports wireless communication and next generation network testing at millimeter wave bands, defense and military applications, radar and satellite systems for K and Ka band operations, as well as teaching and research in university labs. This wide range of uses makes the antenna a practical investment for facilities that handle different types of millimeter wave measurement work.

In practical use, this EMC Measurement Antenna handles professional test tasks at high frequencies very well. For EMC chambers, it serves as a reliable antenna for both radiated emission and radiated immunity testing up to 40GHz. 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 copper aluminum composite construction provides excellent electrical performance while keeping the antenna weight reasonable for mounting on precision positioners and stands. The wide bandwidth means users do not have to stop and change antennas when sweeping across different frequency bands from 18GHz to 40GHz. The 13.5dB minimum gain ensures excellent signal to noise ratio for most millimeter wave measurement setups. It stands as a solid example of how a well designed Double Ridged Horn can meet the demanding needs of modern EMC testing, antenna measurement, and communication system validation at K and Ka bands.
