Products> Antenna Products > Dual Ridged Horn Antennas
Mi-Wave’s Series 265 Dual Ridged Horn Antennas are precision-engineered, ultra-wideband antennas designed to deliver continuous frequency coverage, stable radiation patterns, and reliable electrical performance across a wide operating range from 7 GHz to 70 GHz. These antennas are widely used in applications that require broadband operation, predictable gain, and consistent beam characteristics across multiple RF and microwave bands.
The dual ridged horn design incorporates internal metallic ridges within the horn structure to lower the cutoff frequency and significantly extend the operational bandwidth compared to conventional horn antennas. This enables a single Series 265 antenna to cover multiple frequency bands without gaps, reducing system complexity and eliminating the need for multiple narrowband antennas.
Series 265 dual ridged horn antennas are well suited for EMC and EMI testing, antenna characterization, RF measurement, communications, radar systems, and research environments, where wideband performance and repeatability are essential.
Note: The dual ridged horn antennas shown on this website represent only a portion of Mi-Wave’s manufacturing capabilities. Mi-Wave designs and builds a wide range of additional dual ridged horn antenna configurations beyond those listed, including custom frequency ranges, connector interfaces, polarization options, and mechanical designs.

How Dual Ridged Horn Antennas Work
RF energy is fed into the antenna through a coaxial or waveguide transition and propagates into the horn structure. The dual ridges inside the horn alter the electromagnetic field distribution, lowering the cutoff frequency and enabling wideband operation.
As the signal travels through the horn flare, the electromagnetic fields are smoothly transformed into free-space radiation, producing:
-
Broadband impedance matching
-
Controlled beam shape
-
Reduced reflections and signal distortion
-
Stable radiation patterns across the operating band
