How to Connect a Waveguide Feed to a Dish Antenna
When connecting the waveguide (e.g., WR-90, 1.27×0.64cm), align it with the antenna’s polarization direction. Adjust the feed’s phase center to the paraboloid’s focal point (error < λ/10, <0.3cm at 10GHz). After the flange is snug, tighten the screws evenly to prevent deformation. Principle Anyone in satellite communications knows that a 1.2-meter Ku-band parabolic antenna (f/D=0.6, […]
