The lens horn controls the 94GHz wavefront distortion to <λ/50 through refraction of the PTFE dielectric layer. Combined with the optimization of the Brewster angle of 68.5°±0.3° and ultra-precision machining of Ra<0.8μm, the mode purity is increased to 98.2%. The actual measurement reduces the EIRP fluctuation of the W-band satellite antenna to ±0.35dB (ITU-R S.1327
