Apparatus and method for providing diversity service antenna in portable terminal

Abstract

An apparatus and method configure a diversity antenna in a portable terminal. The apparatus includes a first antenna, a second antenna, a first communication unit for processing a first communication scheme signal communicated through the first antenna, a second communication unit for processing a second communication scheme signal communicated through the second antenna, and a control unit for configuring the first antenna as a diversity antenna for the second communication unit when the first communication unit is not driven.

What is claimed is: 
     
         1 . A portable terminal, comprising:
 a first antenna;   a second antenna;   a first communication unit configured to process a first communication scheme signal communicated through the first antenna;   a second communication unit configured to process a second communication scheme signal communicated through the second antenna; and   a control unit configured to configure the first antenna as a diversity antenna for the second communication unit in consideration of a communication environment of the second communication unit when the second communication unit is driven,   wherein the second communication unit is configured to process second communication scheme signals communicated through the first antenna and the second antenna when the first antenna is configured as the diversity antenna, and   wherein the communication environment of the second communication unit includes at least one of a fading and an electric field strength of a signal communicated by the second communication scheme.   
     
     
         2 . The portable terminal of  claim 2 , wherein the first communication scheme includes a Time Division Duplex (TDD) communication scheme, and
 the second communication scheme includes a TDD communication scheme or a Frequency Division Duplex (FDD) communication scheme.   
     
     
         3 . A method for configuring a diversity antenna in a portable terminal including two or more communication units processing signals of different communication schemes, comprising:
 determining a communication environment of a second communication unit when the second communication unit is driven;   connecting a first antenna to the second communication unit in consideration of the communication environment of the second communication unit; and   processing, by the second communication unit, second communication scheme signals communicated through the first antenna and a second antenna,   wherein the first communication unit processes a first communication scheme signal communicated through the first antenna,   wherein the second communication unit processes a second communication scheme signal communicated through the second antenna, and   wherein the communication environment of the second communication unit includes at least one of a fading and an electric field strength of a signal communicated by the second communication scheme.   
     
     
         4 . The method of  claim 3 , wherein the first communication scheme includes a Time Division Duplex (TDD) communication scheme, and
 the second communication scheme includes a TDD communication scheme or a Frequency Division Duplex (FDD) communication scheme.
