Description
Dual-feed, dual-frequency wideband horn lens antennas provide a compact, high-performance solution for multi-band RF systems operating from 10 GHz to 170 GHz. These antennas combine a broadband horn design, precision dielectric lens shaping, and a dual-port feed architecture to deliver high gain, low sidelobe levels, and excellent polarization purity across multiple frequency bands using a single physical aperture.
This integrated approach allows system designers to support multiple RF functions while reducing antenna count, conserving space, and simplifying overall system architecture.
Note: The antennas shown represent only a portion of Mi-Wave’s dual-feed and wideband horn lens antenna offerings. Custom designs are available to support unique frequency bands, dual-band combinations, gain targets, and system-specific requirements.
Dual-Feed Architecture
The dual-feed configuration uses two physically independent feed ports, each capable of operating on its own RF channel. This allows support for different frequency bands or orthogonal polarizations, such as vertical and horizontal, without requiring additional antennas.
By consolidating multiple RF paths into a single aperture, the dual-feed architecture:
-
Reduces platform size and weight
-
Minimizes mechanical complexity
-
Improves system integration and alignment
-
Supports flexible multi-band or multi-polarization operation
Dual- and Four-Frequency Operation
Dual-Frequency Mode
In dual-frequency operation, each feed port is optimized for a dedicated frequency band. For example:
-
Port A operating in W-Band
-
Port B operating in Ka-Band
This configuration enables simultaneous or switchable multi-band operation using a single antenna aperture.
Four-Frequency Mode
Four-frequency operation is achieved by integrating a diplexer on each feed port. Each diplexer splits the RF path into two sub-bands, resulting in:
-
Two frequency bands on Port A
-
Two frequency bands on Port B
This configuration supports four independent operating bands from a single antenna, enabling uplink, downlink, telemetry, and auxiliary RF functions simultaneously while maintaining isolation and minimizing cross-interference.
Scalable Aperture Options
These horn lens antennas are available with standard lens diameters of 6, 9, and 12 inches, allowing performance to be scaled to meet specific gain and beamwidth requirements.

What This Antenna Does
Dual-feed, dual-frequency wideband horn lens antennas enable simultaneous or multi-band RF operation from a single physical aperture. By combining independent feed paths with a lens-corrected horn structure, these antennas efficiently transmit and receive signals across multiple frequency bands while maintaining high gain, stable beam patterns, and strong isolation between channels.
This design allows RF systems to support uplink and downlink paths, multiple radar functions, or parallel test bands without deploying separate antennas. The result is improved system efficiency, reduced platform size, and simplified RF architecture while preserving high-performance radiation characteristics across the full 10 GHz to 170 GHz operating range.
