Broadband Reference Horn Antenna

Diamond Engineering has spent the last decade pioneering our broadband reference horn antennas, ensuring they’re capable of consistent gain across wide frequency ranges, eliminating the need to purchase several different antennas.  For example, the DE0540 replaces three standard gain horns making it ideal for antenna characterization. Combining well established antenna design theory in combination with extensive R&D and material testing has produced fantastic results.

The special dielectric cone is where the magic happens – it controls the beamwidth and associated gain.  This digitally optimized lens dramatically improves beam profile and gain. The Diamond Engineering reference horn antenna can be used for measurement and/or super broadband communications.  The wide band operation is well suited for material measurements, time domain and RCS measurements. The excellent match and monotonic gain provide a unique combination of application and performance. Higher low band gain is an available option using a 60 cm ground plane.

These antenna can also likely be tailored to your specific needs by utilizing various lenses.  The lens system is designed for aperture frequency gain characteristics (i.e. gain increases with frequency). When used in communications, the gain compensates cable and device frequency losses. The output terminals of the DE0540 are ∞ ohms.

A special modification can be utilized so that the terminal impedance is 50 ohm from DC through 40GHz. This makes it possible to use a single ended amplifier stage for ultra-low noise operation which eliminates the balanced, more costly LNA.  Please see more detailed information below on the various models we offer.
