WI Series • X-Band (8.2 – 12.4 GHz)
FT-RF WR90 Waveguide Input Antenna
FT-RF WR90 Waveguide Input Antenna is a precision-engineered X-Band waveguide input antenna (8.2 GHz to 12.4 GHz) designed for seamless integration into high-frequency waveguide systems. With an optimized input structure, it provides excellent signal coupling and stable radiation characteristics for defense radar cross-section (RCS) testing, anechoic chamber calibration, and high-precision measurement systems.
Constructed from high-precision CNC machined aluminum alloys, this antenna guarantees high cross-polarization rejection (>30 dB) and smooth gain flatness across the entire frequency band, ensuring reliable and repeatable measurement results in laboratory environments.
