Product Description
Mi-Wave’s Series 258 Horn Lens Antennas combine the broadband performance of a horn antenna with the enhanced directivity and focused beam control of a dielectric or metal lens. These high-gain, wideband antennas are engineered for demanding RF, microwave, millimeter-wave, and satellite communication applications where precise beam shaping, low sidelobe levels, and stable patterns are essential.
Designed for rugged environments and lab settings alike, Mi-Wave horn lens antennas deliver consistent performance across a broad range of frequencies, making them ideal for communication links, radar systems, test and measurement, and advanced RF system deployment.
Note: The horn lens antennas shown here represent only a portion of Mi-Wave’s antenna design capabilities. Custom horn lens antenna designs are available to support unique frequency bands, specific gain requirements, polarization, or environmental conditions.

What This Product Does
High-Gain, Wideband Antenna Radiation
Horn lens antennas are specialized antennas that use a horn feed to launch electromagnetic waves into a lens structure, which then focuses and shapes the beam. The horn feed provides a broadband match to the transmission line, while the lens enhances directivity, gain, and control over sidelobe levels.
By focusing RF energy into a tighter beam, horn lens antennas improve signal reach, reduce interference, and support high-precision communications and measurement tasks. This combination of broadband feed and lens focusing enables stable performance across wide frequency ranges.
Why Gain and Beam Control Matter
In many RF and microwave systems, gain and beam pattern directly impact system performance:
-
Higher gain increases effective radiated power and improves link reliability.
-
Narrow beamwidth enhances spatial resolution and reduces off-axis interference.
-
Stable radiation patterns support consistent system behavior across frequency bands.
Horn lens antennas are particularly useful in systems requiring directional control, long-range communication, signal testing, and precision measurement.
