Abstract

The invention provides an antenna control apparatus. The apparatus is applied to electronic equipment provided with at least two antennas. The antenna control apparatus comprises a control circuit connected with a first antenna; when a first detector detects that a second antenna is operating, and when a second detector detects that the first antenna and the second antenna satisfy a preset condition, a controller adjusts parameters of the first antenna by changing the parameter changes of the control circuit to adjust a first influence value of the influence on the second antenna from the first antenna into a second influence value, wherein the second influence value is less than the first influence value. By adoption of the antenna control apparatus, when one of two adjacent antennas is in operation, the influence on the running antenna from the other antenna can be reduced by changing the parameters of the control circuit connected with the other antenna; namely, the influence on the energy for outward radiation from the signal emitted from the running antenna is reduced; the efficiency loss of the working antenna is reduced, and signal transmission efficiency of the electronic equipment with multiple antennas is improved.

Description

technical field [0001] The present invention relates to the field of mobile terminals, and more specifically, relates to an antenna control device, method and electronic equipment. Background technique [0002] With the advancement of electronic technology, more and more antennas are installed in electronic equipment, and each antenna corresponds to a specific frequency band to realize receiving and sending of signals in the frequency band. [0003] Since each antenna in an electronic device uses a conductor and sends signals to the external space through the conductor antenna, when the space distance between any two antennas is relatively close, due to the inductive characteristics of the conductor, the connection between two antennas using the same material It is easy to generate induction between the working antennas, that is, when one antenna is working, the other antenna will absorb the signal energy sent by the working antenna, resulting in the reduction of the energy ...
