Antenna apparatus of mobile terminal

Abstract

A mobile terminal and manufacture of same are provided. The mobile terminal includes: an antenna; a first case at which the antenna is disposed; a second case coupled to the first case; a main PCB disposed at one side of the second case; and a sub-PCB disposed at an opposite side of the second case, the sub-PCB being connected to the main PCB through a cable, wherein the sub-PCB is electrically coupled with the antenna when the first case and the second case are coupled together.

What is claimed is: 
     
         1 . A portable communication device comprising:
 a case forming at least part of an outer surface of the portable communication device; a first printed circuit board (PCB) disposed in a first portion of an inner space of the case;   an antenna including a contact point disposed in the inner space of the case and facing the first portion of the inner space of the case, and a radiating element electrically coupled with the first PCB via the contact point.   
     
     
         2 . The portable communication device of  claim 1 , wherein the first PCB comprises a contact terminal directly contacted with the contact point. 
     
     
         3 . The portable communication device of  claim 2 , wherein the first PCB further comprises another contact terminal contacted with another contact point of the antenna, and
 wherein the first PCB is configured to support a first specified communication scheme using the antenna via the contact terminal and a second specified communication scheme using the antenna via the other contact terminal.   
     
     
         4 . The portable communication device of  claim 3 , wherein the first PCB comprises switch circuitry to select a communication signal path corresponding to at least one of the contact terminal or the other contact terminal, based at least in part on a communication scheme selected between the first specified communication scheme and the second specified communication scheme. 
     
     
         5 . The portable communication device of  claim 3 , wherein the first specified communication scheme corresponds to a first frequency band and the second specified communication scheme corresponds to a second frequency band. 
     
     
         6 . The portable communication device of  claim 1 , wherein the case comprises a first housing and a second housing, wherein the first housing is mechanically coupled with the second housing. 
     
     
         7 . The portable communication device of  claim 1 , wherein the first PCB comprises an impedance matching circuit electrically connected to the antenna to adjust an impedance corresponding to the antenna. 
     
     
         8 . The portable communication device of  claim 1 , wherein:
 the first PCB further comprises at least one hole, and   the first PCB is fastened to the case via the at least one hole.
