2-18GHz Quad Ridged Dual Polarized Horn Antenna

Dual Linear Polarization Horn Antenna 2-18GHz Quad Ridged Design

This product is a high performance Dual Polarized Horn Antenna featuring a quad ridged waveguide design. The antenna operates from 2GHz to 18GHz and is built from aluminum for light weight and good durability. As a Quad Ridged Dual Polarized Horn, it offers ultra wideband coverage of up to multiple frequency decades. The antenna features low cross polarization and a compact structure that is smaller in size compared to other designs at the same frequency. This makes it well suited for space constrained scenarios such as base stations and airborne platforms. The antenna offers dual linear polarization and comes with an SMA K type connector for easy integration with standard test equipment. By adding a 90 degree hybrid coupler, users can quickly switch to dual circular polarization.

This dual polarized horn antenna delivers solid electrical performance across its ultra wide operating range from 2GHz to 18GHz. The Voltage Standing Wave Ratio (VSWR) is rated at 2.5, which shows good impedance matching for an ultra wideband design covering multiple frequency decades. The gain is 5dB or higher, providing sufficient signal strength for most test and measurement tasks. The port isolation is 20dB or higher, ensuring minimal interference between the two polarization channels. The compact ridged structure provides excellent mechanical strength while keeping the overall size small. The aluminum construction ensures long term reliability even with frequent handling. The design also provides good shielding against outside interference. The SMA K connector is a precision type suitable for high frequency work up to 18GHz.

One clear strength of this Quad Ridged Dual Polarized Horn is its exceptional bandwidth and polarization flexibility. It is widely used for ultra wideband measurement, reflector antenna feed systems, next generation communication and millimeter wave testing, EMC and microwave anechoic chamber measurements, as well as radar and electronic warfare applications. The dual linear polarization capability allows engineers to characterize antennas and systems under different polarization states. When a 90 degree hybrid coupler is added, the antenna can operate in dual circular polarization mode, further expanding its application range. For engineers working on wideband radar systems, this antenna provides reliable performance across the entire 2-18GHz band without needing to change antennas. For EMC test laboratories, the compact size and wide bandwidth make it a practical choice for chamber installations where space is limited.

In practical use, this Quad Ridged Dual Polarized Horn handles professional test tasks very well. For antenna measurement ranges, it serves as a reliable feed antenna for reflector systems or as a reference antenna for polarization characterization. The ability to switch between linear and circular polarization by adding a 90 degree hybrid coupler gives users flexibility to meet different test requirements. For electronic warfare and reconnaissance applications, the ultra wideband coverage allows detection and analysis of signals across multiple bands. The compact size makes it easier to integrate into airborne or vehicle mounted systems where weight and volume are important considerations. The aluminum construction keeps the antenna light while providing good durability. The SMA K connector is precise and suitable for repeated connections. It stands as a solid example of how a well designed Quad Ridged Dual Polarized Horn can meet the demanding needs of ultra wideband measurement, radar, and communication applications from 2GHz to 18GHz.
