1. A built-in antenna device disposed within a housing of an electronic communication device, the built-in antenna device comprising:
- a printed circuit board (“
PCB”
);
a first antenna radiator formed as a metal pattern on a surface of the PCB and spaced from an inner surface of the housing; and
a second antenna radiator which is fed from the same power feeding point as the first antenna radiator and having a first portion extending from a power feeding terminal thereof towards the inner surface of the housing and being bent in a transition to a second portion that is attached to and runs along the inner surface, the second antenna radiator being in a form of a wire radiator, a metal plate of a defined pattern, or a Flexible Printed Circuit (FPC) including a metal pattern;
wherein the first antenna radiator and the second antenna radiator are configured with different lengths so as to operate in different frequency ranges such that the antenna device is operable as a dual band antenna, andthe first and second antenna radiators are installed opposing one another within the housing.

14. A built-in antenna device disposed within a housing of an electronic communication device, the built-in antenna device comprising:
-
a printed circuit board (PCB); a first antenna radiator formed as a metal pattern on a surface of the PCB and spaced from an inner surface of the housing, and extending from a power feeding portion to a first free end; and a second antenna radiator which is fed from the same power feeding point as the first antenna radiator and having a first portion extending from a power feeding terminal towards the inner surface of the housing and being bent in a transition to a second portion that is attached to and runs along the inner surface, the second antenna radiator being in a form of a wire radiator, a metal plate of a defined pattern, or a Flexible Printed Circuit (FPC) including a metal pattern; wherein the first antenna radiator and the second antenna radiator are configured with different lengths so as to operate in different frequency ranges such that the antenna device is operable as a dual band antenna, and the first and second antenna radiators are installed opposing one another within the housing, in which the second portion of the second antenna radiator transitions via a U-shaped transition to a third portion that extends to a second free end located on an opposite side of the electronic communication device as the first free end.
