Problems solved by technology
[0004] The disadvantage of this technology is that the metal conductor is arranged closer to the communication partner than the coil, and the coil is attached to one side of the metal conductor, so if a thin three-dimensional structure cannot be placed on the metal conductor, it is impossible to use three-dimensional parts on communication equipment such as earpieces , is a planar structure antenna, and the communication performance of this structure needs to be improved

The invention provides a three-dimensional near-field antenna structure comprising a conductor plate member and an antenna module. The conductor plate member is provided with an opening part enabling the upper and lower surfaces of the conductor plate member to be communicated. The opening part extends to one side edge of the conductor plate member via an opening arranged on the opening part, and the extension part forms a through slot enabling the upper and lower surfaces of the conductor plate member to be communicated. The antenna module comprises a coil which is fixed in the opening part. Insulating part material is arranged between the coil and the opening part so that mutual insulation can be realized. The coil is internally arranged in the conductor plate member so that spatial intensification of the antenna structure is realized. Besides, the conductor plate member is enabled to be used for installing three-dimensional components so that mobile terminal miniaturization is further facilitated and communication performance is enhanced.
Description
technical field [0001] The present invention relates to the field of antennas, in particular to a three-dimensional near-field antenna structure suitable for an NFC (Near Field Communication) antenna or an RFID (Radio Frequency Identification) antenna. Background technique [0002] NFC and RFID technology realize wireless communication between two or more devices through electromagnetic induction coupling. With the popularity of this communication method in the world, coils are used as emitters of NFC and RFID in mobile devices. It is also getting higher and higher, mainly in mobile phones. [0003] The casing of many mobile phones is a metal conductor. Since electromagnetic waves cannot penetrate the conductor, the metal material will have a great impact on the antenna magnetic field. For example, eddy current loss may occur, weaken the magnetic field energy, change the magnetic field direction, etc., which will affect the communication performance. To reduce the impact an...
