The present invention discloses an electronic device and an antenna device thereof. The antenna device comprises an artificial magnetic conductor structure, an antenna unit and a circuit mainboard, wherein the artificial magnetic conductor structure comprises a dielectric layer, a conductive layer arranged on the surface of one side of the dielectric layer and a plurality of conductive pasters which are arranged on the surface at the other side of the dielectric layer and are arranged on the surface of the dielectric layer periodically, the antenna unit is arranged at one side of the artificial magnetic conductor structure and is insulative with the artificial magnetic conductor structure, and the circuit mainboard is arranged at the other side of the artificial magnetic conductor structure and comprises a communication device; an antenna is connected with a feed point of the communication device via a feeder line. The antenna device and the electronic device possessing the antenna device have a higher radiation efficiency, at the same time, the radiation of the antenna device and the electronic device possessing the antenna device to the human body is smaller when the antenna device and the electronic device possessing the antenna device are used.
Description
technical field [0001] The present application relates to the technical field of antenna devices, and more specifically, to an electronic device and an antenna device thereof. Background technique [0002] The radio signal output by the radio transmitter is sent to the antenna through the feeder, and is radiated by the antenna in the form of electromagnetic waves. After the electromagnetic wave reaches the receiving location, it is followed by the antenna and sent to the radio receiver through the feeder. It can be seen that the antenna is an important radio equipment used by communication equipment to transmit and receive electromagnetic waves. Without antennas, there would be no electronic equipment used for radio communication today. [0003] Since the human body can absorb electromagnetic waves, the radiation efficiency of antennas of electronic devices will be low. On the other hand, electromagnetic wave radiation will affect human health. Therefore, how to provide an...
