Millimeter-wave planar slotted-waveguide arrays antennas of short range airborne missile are studied in this paper. The manufacturing error of antennas directly affects its electromagnetic performance. In order to fulfill the demanded precision in manufacture, the effect of the structural errors of the antenna parts on its performances is studied.
In the paper, firstly, the structural and manufacture characterizations of the antenna are presented. Secondly, the theory of the antenna is introdu...
