Dual Polarized Horn Antenna 18dBi Typ.Gain, 75GHz-110GHz Frequency Range RM-DPHA75110-18

Short Description:

The RM-DPHA75110-18 is a full-band, dual-polarized, WR-10 horn antenna assembly that operates in the frequency range of 75 to 110GHz. The antenna features an integrated orthogonal mode converter that provides high port isolation. The RM-DPHA75110-18 supports vertical and horizontal waveguide orientations and has a typical 40 dB cross-polarization isolation, a nominal gain of 18 dBi at the center frequency, a typical 3db beamwidth of 22 degrees in the H-plane, a typical 3db beamwidth of 33 degrees in the V-plane. The input to the antenna is a WR-10 waveguide with a UG-387/U-M threaded flange.

  • The dual-polarized horn antenna is a precision microwave antenna capable of simultaneously supporting two orthogonal polarized waves (typically ±45° linear polarization or left/right-hand circular polarization). It employs an integrated ortho-mode transducer (OMT) to achieve polarization separation, featuring high port isolation (>30 dB), low cross-polarization (<-25 dB), and broad bandwidth (typically with a 2:1 frequency ratio). While retaining the inherent advantages of horn antennas, such as high gain (10-25 dBi) and low voltage standing wave ratio (VSWR <1.5), the dual-channel design enhances channel capacity and mitigates multipath fading. This antenna is widely used in high-end applications requiring polarization information processing, including 5G millimeter-wave base stations, satellite communication polarization diversity, EMC testing, and radar target identification.
