The purpose of the present invention is to improve orientation characteristics of planar antennas for millimeter waveband use and to increase bandwidth. [Solution] A power supply line (13) having a main power supply line (21), two auxiliary power supply lines (22), and a distributor (S2) that branches the main power supply line (21) into the two auxiliary power supply lines (22). The distributor (S2) comprises: two outer edges (30L, 30R) comprising a curve connecting both side edges (21L, 21R) of the main power supply line (21) to first edges (221) of the auxiliary power supply lines (22); and an inner edge (31) connecting second edges (222) of the auxiliary power supply lines (22) to each other. The inner edge (31) comprises two inner curves (31L, 31R) that are each curved outwards towards the other and has a pointed shape recessed towards the main power supply line (21) side. |
