RADAR ANTENNA

摘要

Provided is a radar antenna integrally formed on a dielectric radiation board to prevent occurrence of surface wave and capable of wide angle measurement. The radar antenna 400 has eight antenna units 410 formed on a radiation board 420 in 4 by 2 arrangement. On a back surface of the radiation board 420, a first ground plate 401 is formed, and a line board 405 is further formed on the first ground plate 401. A radiation part 402a is pattern-formed on the radiation board 420 and a power feeding part 402b is formed to be a through hole and connected to a transmission line 404. A second ground plate 403 has a land 403a pattern-formed on the radiation board 420 and a through hole 403b.
