An electronic device is disclosed. The electronic device includes a conductive plate, an opening, two feeding parts, and an electronic assembly. The opening is disposed at a side of the conductive plate. The opening has a first side and a second side opposite to each other, and the first side and the second side are connected with the side of the conductive plate. The electronic assembly is located in the opening. Two feeding parts are respectively disposed on the first side and the second side of the opening. the feeding parts is used to receive a feeding signal, and the feeding signal is transmitted along the first side of the opening to the second side of the opening and generates a near field magnetic field.

Electronic device and near field communication antenna thereof

An antenna module is provided. The antenna module includes a circuit board, a conductive layer, and a spiral coil. The circuit board has a first surface and a second surface opposite to each other. The circuit board further includes a first block and a second block connected to each other. The conductive layer is disposed on the first block. The spiral coil is disposed in the second block of the circuit board. The conductive layer at least partially surrounds the spiral coil.

Antenna module and electronic device including the same

An electronic device is provided. The An electronic device comprises a near field communication (NFC) circuit for transmitting a set of near field communication differential signals including a first differential signal and a second differential signal; a housing including a conducting portion with a ground point, a first side and a second side opposite to the first side; and two conductive arms. A current loop is formed by the conductive arm and the conducting portion, and a potential of the ground point is equal to a median potential of the current loop.

Electronic device

A connection apparatus and a portable system thereof are connected to a traffic message channel (TMC) device through a universal serial bus (USB) port. The portable system includes a satellite navigation device for performing a positioning function through the global positioning system and displaying a traffic message through a display interface, a USB port connecting to the TMC device to transmit the traffic message to the satellite navigation device, and a switch device for determining whether the connecting device is a USB device or a TMC device and switching the transmission standard and power supply mode thereof.

Connection apparatus and portable system thereof

An apparatus and its corresponding method for switching a light source are provided. The apparatus includes a light sensor, a decision device and a light source. The light sensor senses the ambient luminance and outputs a sensing signal to indicate whether the luminance is greater than a predetermined quantity. The decision device is connected to the light sensor. It receives a switching signal and outputs a lighting signal according to the sensing signal and the switching signal. The light source is coupled to the decision device and is activated whenever the lighting signal demands light.
