6to40GHz Quad Ridged Dual Circular Horn Antenna

This product is a versatile Dual Circular Polarization Horn Antenna featuring a quad ridged design with a 3dB hybrid coupler. The antenna operates from 6GHz to 40GHz and is built from aluminum for light weight and good durability. As a Quad Ridged Dual Polarized Horn, it offers ultra wideband circular polarization coverage far better than septum polarizers which have narrow bandwidth. With the hybrid coupler attached, the antenna provides circular polarization across multiple frequency decades. When the coupler is removed, the antenna works as a Dual Linear Polarization Horn. This gives users two functions in one antenna. The quad ridged structure integrates dual polarization without needing an external orthomode transducer, making the system more streamlined. The antenna features a precision 2.92mm K type connector.

This circular polarized horn antenna delivers solid electrical performance across its ultra wide operating range from 6GHz to 40GHz. The Voltage Standing Wave Ratio (VSWR) is rated at 1.7, which shows good impedance matching across this very wide bandwidth. The typical gain is 10dB, providing sufficient signal strength for most test and measurement tasks. The port isolation is 10dB or higher, and the axial ratio is 6.0dB or lower. The beam is uniform with symmetrical E plane and H plane patterns and low cross polarization. This makes the antenna suitable as a feed or test antenna. The aluminum construction ensures long term reliability even with frequent handling. The 2.92mm K connector is a precision type suitable for high frequency work up to 40GHz.

One clear strength of this Quad Ridged Dual Circular Horn is its excellent balance between ultra wide bandwidth, polarization flexibility, and moderate cost. It is ideal for electronic warfare and wideband reconnaissance接收 systems, telemetry tracking and control, space ranges, portable satellite communication and on the move terminals, microwave anechoic chamber testing, electromagnetic compatibility testing, radar and low altitude security, as well as next generation communication and private network systems. The polarization flexibility is a key advantage. Remove the hybrid coupler and the antenna becomes a dual linear polarization horn for traditional measurements. Add the coupler back and it works as a circular polarization antenna for satellite and radar applications. This one antenna serves multiple purposes. The cost is moderate compared to premium OMT based solutions while performance is much better than simple septum polarizer designs.

In practical use, this Dual Circular Polarization Horn handles professional tasks very well. For electronic warfare and reconnaissance applications, the ultra wideband coverage from 6GHz to 40GHz allows detection and analysis of signals across multiple bands without changing antennas. For telemetry tracking and control, the ability to switch between linear and circular polarization gives operators flexibility to work with different systems. For portable satellite communication terminals, the compact design and moderate gain provide reliable links. For anechoic chamber testing and antenna measurement ranges, the symmetrical pattern and low cross polarization help produce accurate results. The 2.92mm K connector is precise and suitable for repeated connections. The aluminum construction keeps the antenna light for easy transport and mounting. It stands as a solid example of how a well designed Quad Ridged Dual Circular Horn can meet the demanding needs of wideband reconnaissance, test, and communication applications from 6GHz to 40GHz.
