The second radiating unit includes a third radiating element, a fourth radiating element, a second turning portion located between the third radiating element and the second end and a third turning portion located between the third radiating element and the fourth radiating element. A distance is formed between the fourth radiating element and the ground surface.

An antenna device. The antenna device includes a printed circuit board, a conductive shield, a first connection portion and a second connection portion. The printed circuit board has a feed point and a ground plane insulated from the feed point. The conductive shield surrounds the printed circuit board. The first connection portion is substantially perpendicular to the printed circuit board, electrically connecting the feed point and the conductive shield. The second connection portion is substantially perpendicular to the printed circuit board, electrically connecting the ground plane and the conductive shield.

Antenna device

An antenna module includes a circuit board, a differential-type amplifier, and a dipole antenna. The dipole antenna can be formed with two electrodes disposed on the circuit board. With the structure of the antenna module, a transmitting antenna can be designed by coupling the two electrodes of the dipole antenna to output terminals of the differential-type amplifier so as to transmit signals. In design of a receiving antenna, the two electrodes of the dipole antenna can be coupled to input terminals of the differential-type amplifier so as to receive signals. Further, if the main function chip has built-in differential power amplifier or differential low noise amplifier, a circuit module for wireless signal transmitting and receiving can be formed by directly coupling the dipole antenna to the differential power amplifier or the differential low noise amplifier.
