2-4GHz Broadband Horn Antenna

Broadband Horn Antenna 2-4GHz

This product is a professional Broadband Horn Antenna designed for S band applications requiring good performance and cost effectiveness. The antenna operates from 2GHz to 4GHz 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.

This broadband horn antenna delivers solid electrical performance across its operating range from 2GHz to 4GHz. The Voltage Standing Wave Ratio (VSWR) is rated at 1.6, which shows excellent impedance matching. The gain is 10dB or higher, providing strong signal strength for most 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.

One clear strength of this Wideband Test Antenna is its excellent balance between performance and cost. It is widely used for EMC electromagnetic compatibility chamber testing, where consistent performance across the S band 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 research, it helps with development and calibration tasks. For electromagnetic interference troubleshooting and radiation monitoring, this antenna provides reliable detection across the 2-4GHz band. The antenna also supports wireless communication and network testing, defense and military applications, radar and satellite systems, 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 good performance without paying for ultra wideband capabilities they do not require.

In practical use, this EMC Horn handles professional test tasks very well. For EMC chambers, it serves as a reliable antenna for both radiated emission and radiated immunity testing in the S band. 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. The aluminum construction keeps the antenna light enough for easy mounting on positioners and stands. The low VSWR of 1.6 ensures good impedance matching and minimal signal reflection. The 10dB minimum gain provides sufficient signal to noise ratio for most measurement setups. 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 S band while offering excellent value for money.
