Description & Specification
26.5 GHz to 40.0 GHz WR-28 Ka-Band E-Plane Sectoral Horn Antenna
Fan-Beam Radiation Pattern | Direct Waveguide Input | Model: HS-028-UBR-15-NA
The HS-028-UBR-15-NA is a precision-engineered Ka-Band E-Plane Sectoral Horn Antenna professionally designed and manufactured by Fei Teng Wireless Technology Co., Ltd. (FT-RF) for specialized wide-horizontal illumination fields. Operating within the millimeter-wave spectrum across the continuous 26.5 GHz to 40.0 GHz frequency band, this premium antenna is expertly flared in the E-plane to deliver a distinct, highly predictable Fan-Beam radiation pattern profile (77° H-plane x 16° E-plane) combined with a calibrated nominal gain of 15 dBi. Featuring a Direct Waveguide Input interface with a standardized UG-599/U (UBR Style) flange mating face, it ensures flawless structural impedance coplanarity and ultra-low-loss power transfer, safely managing continuous wave power loads up to 500 Watts (CW). Precision CNC machined from high-grade structural alloy in Taiwan, it exhibits exceptional electromechanical longevity and excellent pattern isolation metrics. It stands as the definitive choice for wide-vertical beam scanning grids, automated antenna characterization ranges, industrial EMI/EMC compliance validation scanning, professional 5G mmWave research, and mission-critical satellite link verification setups demanding uncompromised performance parameters.
