A waveguide correlation unit and a method for its manufacturing

摘要

A waveguide correlation unit and a method for manufacturing the same are disclosed. The waveguide correlation unit comprises stacked first and second waveguide plates having an identical configuration, wherein a central coupling plate is disposed therebetween. Due to the identical configuration of the first and second waveguide plates, mechanical uncertainties may significantly be reduced, since both plates may be formed in a common process without the repositioning activities during the manufacturing process.
