There is provided an antenna that enables easy soldering of an external conductor of a coaxial cable to a ground pattern. An antenna devicecapable of transmitting and receiving a radio wave includes a coaxial cablehaving a center conductorand an external conductorand an antenna element. The antenna elementhas an antenna patternand a ground pattern. The center conductoris soldered to a first solder portionof the antenna pattern, and the external conductoris soldered to a second solder portionof the ground patternby means of solder. The ground patternhas an openingdefining the second solder portion. The second solder portionis provided between the first solder portionand the opening

Antenna device

Antenna

In a planar antenna including a board having an upper surface on which a planar antenna element pattern is formed, a probe for feeding to the planar antenna element pattern by electromagnetic coupling, a ground plate, and a base having a groove for disposing the probe therein, the planar antenna has a fastening member for fastening the board to the ground plate with the base sandwiched therebetween. The fastening member has a case, disposed on the upper surface of the board, having four bosses which extend downwards and which have four screw holes and four screws threaded to the four screw holes from the ground plate side.
