Mobile terminal and antenna controlling method

Abstract

The invention provides a mobile terminal and an antenna controlling method. The mobile terminal comprises a first shell and a second shell which have a folded or unfolded state; wherein a grounded first radiation arm which is electrically isolated from the first shell is arranged at one side edge of the first shell; the first shell is provided with a first electrical contact and a second electrical contact; the first electrical contact is electrically connected with the first radiation arm; the second electrical contact is electrically connected a grounded first signal source; a grounded second radiation arm which is electrically isolated from the second shell is arranged at one side edge of the second shell; the second shell is provided with a third electrical contact and a grounded fourth electrical contact; the third electrical contact is electrically connected with the second radiation arm; and when the first shell and the second shell are in the folded state, the first electricalcontact is in contact with the fourth electrical contact to conduct and the second electrical contact is in contact with the third electrical contact to conduct. The mobile terminal provided by the invention can be better applied to the usage scenarios with high performance requirements for NFC (Near Field Communication) antennas when the mobile terminal is in the folded state.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a mobile terminal and an antenna control method. Background technique [0002] In order to realize functions such as mobile payment, bus travel, reading NFC electronic tags or recharging NFC cards, etc., a near field communication (Near Field Communication, NFC) antenna needs to be installed on the mobile terminal. The NFC antenna communicates through magnetic field coupling, which is generally realized by a coil or a closed loop equivalent to a coil. The magnetic flux of the coil or closed loop directly affects the performance of the NFC antenna during operation. [0003] Some existing mobile terminals are limited by structure or other factors, and cannot use conventional methods to wind multi-turn coils to form NFC antennas. Therefore, metal shell structures are usually used as NFC antennas. This kind of mobile terminals that use metal shell structures as NFC ant...
