An antenna device and a wideband antenna apparatus are provided to cover a usage frequency band of a UWB(Ultra Wide Band) by a folded plate-shaped monopole antenna unit after covering a usage frequency band of a mobile phone by a first conductor device and a second conductor device. An antenna device comprises a folded plate-shaped monopole antenna unit(44), a first conductor device(46), and a second conductor device(47). The folded plate-shaped monopole antenna unit has a U-shaped cross section, and includes a first conductor plate(441), a second conductor plate(442), and a connection plate(443). The first conductor plate has a first length. The second conductor plate is parallel arranged to the first conductor plate, and has a second length shorter than the first length. The connection plate connects the first conductor plate to the second conductor plate. The first conductor device is extended from the second conductor plate of the folded plate-shaped monopole antenna unit. The second conductor device is extended from the connection plate of the folded plate-shaped monopole antenna unit. |
