Abstract

The invention discloses an antenna device, a control method for the same and an electronic device. The antenna device comprises a first antenna unit, a second antenna, a frequency band control unit, and a switch unit; the first antenna unit can transmit a first antenna signal including multiple frequency bands; the multiple frequency bands comprise a first frequency band and a second frequency band; the frequency of the second frequency band is different from that of the first frequency band; the second antenna unit can transmit a second antenna signal and the frequency band of the second antenna signal comprises the first frequency band; the frequency band control unit is connected to the first antenna unit and transmits the signal of the second frequency in the first antenna signal between the first antenna unit and a signal transceiver corresponding to the second frequency band; and the switch unit is used for connecting at least one of the frequency band control unit and the second antenna unit to a signal transceiver corresponding to the first frequency band for transmitting the signal of the first frequency band. The antenna device, the control method and the electronic device can avoid insertion loss of a switch unit on transmission paths of part of the antenna signals and improve signal quality of part of the antenna signals.

Description

technical field [0001] The present invention relates to the technical field of communications, and more specifically, to an antenna device, a control method for it, and electronic equipment. Background technique [0002] With the development of communication technologies, electronic devices may use different communication technologies to transmit voice, data, and the like. Some electronic devices use two antennas to ensure communication quality. For example, using a diversity antenna in conjunction with the main antenna in a mobile phone can effectively improve the sensitivity of the mobile phone to receive wireless signals in harsh environments. [0003] Usually, a switch is set to select the antenna to be used for communication from among the two antennas. For example, a switch is set between the antenna and the channel of the signal transceiver, and the working state of the switch is changed according to the control of the electronic device, so that the signal received ...
