Abstract: An integrated broadband antenna device with wide band function is disclosed. The antenna device comprises a ground plate, a feeding wire, a first metal radiator, a second metal radiator, a ground metal radiator and a parasitic metal radiator. The first metal radiator is connected with the positive ends of signals of the feeding wire for transmitting electric signals and producing a high frequency mode.
