Dual-Polarized D-Band Waveguide Horn Lens Antenna (RHCP | LHCP)

258D-12/.XXX/387  90 GHz -140 GHz Circular Waveguide with UG-387/U-M Flange | Right-Hand Circular Polarization or Left-Hand Circular Polarization

Product Description

Mi-Wave’s Series 258 RHCP/LHCP Horn Lens Antennas are high-performance directional antennas designed to deliver high gain, low sidelobes, precise beam control, and stable radiation patterns across RF, microwave, and millimeter-wave frequency bands from 8.4 to 220 GHz.

By combining the broadband characteristics of a horn antenna with the focusing capability of a precision lens, these antennas provide enhanced directivity, improved aperture efficiency, and excellent beam shaping performance across wide frequency ranges. The horn-lens architecture enables higher gain and narrower beamwidths than many conventional horn antennas while maintaining low distortion and predictable radiation characteristics.

For circular polarization applications, Series 258 Horn Lens Antennas can be integrated with Mi-Wave’s Series 282 Linear to Circular RF Polarizers to support Right-Hand Circular Polarization (RHCP) or Left-Hand Circular Polarization (LHCP) operation. These configurations help reduce sensitivity to antenna orientation, minimize polarization mismatch losses, and improve signal reliability in satellite communications, telemetry, radar, and advanced RF systems.

For systems requiring dual-linear polarization, Series 258 antennas may also be integrated with Mi-Wave’s Series 281 Orthomode Transducers (OMTs), enabling separate Vertical (V) and Horizontal (H) polarization paths through a shared antenna aperture while maintaining high isolation between channels.

Series 258 RHCP/LHCP Horn Lens Antennas are well suited for satellite communications (SatCom), radar systems, telemetry platforms, antenna measurement ranges, RF laboratories, EMC testing, and millimeter-wave research applications where high gain, stable polarization performance, and precision beam characteristics are required.
