Antenna deviece for portable wireless terminal

The invention The present invention a signal is transmitted from the transmitting sub-antenna and the third frequency band for transmitting a signal of a portable radio according to the antenna device of the terminal, the mobile for processing a signal of a first frequency band communication, the main antenna and the second band received that when credit sub-antenna and the second frequency band and the third frequency band overlap, the transmission sub-antenna and the receiving sub antenna use one selectively of and, and the second frequency band and the third If the band does not overlap, without increasing the volume of the transmission sub-antenna and the can by using an antenna device for a portable wireless terminal comprising: a control unit for controlling so as to use a credit sub antenna at the same time, the portable wireless terminal, it is possible to improve the space available and the radiation performance of the antenna. Antenna, the case frame, a radiator, a battery cover, cell
