Abstract
[Object] To improve the directional characteristics of a planar antenna for a milliwave band as well as widening a bandwidth.[Means for Settlement] A feed line 13 has a main feed line 21, two sub-feed lines 22, and a distributor S2 adapted to branch the main feed line 21 into the two sub-feed lines 22. The distributor S2 includes: two outer edges 30L and 30R formed as curved lines connecting both side edges 21L and 21R of the main feed line 21 to first edges 221 of the sub-feed lines 22; and an inner edge 31 connecting second edges 222 of the sub-feed lines 22 to each other, in which the inner edge 31 is configured to include two inner curved lines 31L and 31R that are convex in mutual directions, and has a pointed shape that is concave toward the main feed line 21 side.
