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

A portable electrical device with a planar antenna for wireless transmitting data includes a host case for assembling a motherboard therein and a display module pivotally connected to the host case. The display module has a housing for containing a display panel and the planar antenna. The planar antenna is connected to the motherboard via a transmitting line for transmitting and receiving the signals to and from the planar antenna.

Portable electrical device with planar antenna

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.
