Method and apparatus for switching antenna in portable terminal

摘要

A method and apparatus of switching an antenna in a portable terminal having a plurality of antennas, a plurality of communication modules, and a switch unit for switching a wireless path are provided. The method includes determining whether a received signal strength of at least one communication module is reduced to or below a preset reference value, measuring, when the received signal strength of the at least one communication module is determined to be reduced to or below the preset reference value, respective received signal strengths of the plurality of the antennas with respect to a frequency band supported by the at least one communication module, and controlling the switch unit, based on the measurement result, such that a wireless path is formed between the at least one communication module and an antenna having a greatest received signal strength among the plurality of the antennas.

1. A method of switching an antenna in a portable terminal having a plurality of antennas, a plurality of communication modules, and a switch unit for switching a wireless path between the plurality of the antennas and the plurality of the communication modules, the method comprising:
determining whether a received signal strength of at least one communication module among the plurality of the communication modules is reduced to or below a preset reference value; measuring, when it is determined that the received signal strength of the at least one communication module is reduced to or below the preset reference value, respective received signal strengths of the plurality of the antennas with respect to a frequency band supported by the at least one communication module; controlling the switch unit, based on the measurement result, such that a wireless path is formed between the at least one communication module and an antenna having a greatest received signal strength among the plurality of the antennas; determining whether the received signal strength of all of the plurality of the communication modules is above the preset reference value; determining, based on the received signal strength of all of the plurality of the communication modules being above the preset reference value, whether a sensor signal, corresponding to at least one of a gripping of the portable terminal and a contact with a human body, is received; measuring received signal strengths of the plurality of the antennas with respect to one or more frequency bands corresponding to respective communication modules of the plurality of the communication modules; and controlling the switch unit such that a wireless path is formed between each of the respective communication modules and an antenna having a greatest received signal strength with respect to a corresponding frequency band, wherein at least two communication modules among the plurality of the communication modules share the antenna having the greatest received signal strength, and wherein each of the plurality of communication modules, independently of each other of the plurality of communication modules, transmits and receives radio signals via the antenna having the greatest received signal strength.
