Title:
METHOD OF PRODUCING A RADIO FREQUENCY MEMBER
Document Type and Number:
WIPO Patent Application WO/2018/190227
Kind Code:
A1
Abstract:
A structure in which rods are arrayed is provided by using a raw material such as resin, and a plating layer is formed on its surface to confer electrical conductivity. In doing so, in order to restrain defects from occurring in the plating layer between rods, a gradually-pointed shape is adopted for the rods, whereby a gap between rods is shaped so as to enlarge toward the upper ends. This makes air voids between rods likely to be discharged with surface tension effects. A ridge to become a waveguide member may also be formed together with rod rows. By adopting a gradually-pointed shape for the rods, gaps between the ridge and the rods also are shaped so as to enlarge toward the rod upper ends, whereby discharging of air voids from between the ridge and the rods is also promoted.
