Abstract

An electronic device includes: a body; a circuit board disposed in the body; and an antenna device mounted to one region of the body, and having first and second antenna units spaced apart from each other by a specific interval, in order to transceive a radio signal at a specific frequency band, wherein each of the first and second antenna units includes: a dielectric substance disposed to form a gap with the circuit board; an antenna chip disposed at the circuit board; and a pair of feeding portions for connecting the antenna chip with the dielectric substance.

First claim

What is claimed is:

1 . An electronic device, comprising:
a body; a circuit board; and an antenna device configured to transceive a radio signal, wherein the antenna device is mounted to the body and comprises first and second antenna units, wherein each of the first and second antenna units comprises: a dielectric substance; an antenna chip disposed at the circuit board; and a pair of feeding portions configured to connect the antenna chip with the dielectric substance, wherein a gap is defined between the dielectric substance and the circuit board.

2 . The electronic device of claim 1 , wherein the feeding portions each comprise:
a first region extending from the antenna chip; and a second region connected to the first region and formed on one surface of the dielectric substance, wherein the first and second regions define a specific angle therebetween.

3 . The electronic device of claim 2 , wherein the specific angle is 90°.

4 . The electronic device of claim 3 , wherein the second region is configured to have a trapezoid shape or an L-shape.

5 . The electronic device of claim 1 , wherein the dielectric substance comprises:
a fixed portion coupled to the circuit board; and a recessed portion, wherein the gap is defined between the recessed portion and the circuit board.

6 . The electronic device of claim 5 , wherein a surface-mount technology (SMT) fixing pad is disposed at the fixed portion.

7 . The electronic device of claim 1 , wherein the circuit board comprises a circuit board recessed portion at a region adjacent to an edge of the dielectric substance, and the gap is defined between the circuit board recessed portion and the dielectric substance.

8 . The electronic device of claim 1 , wherein:
the first and second antenna units are arranged along a first axis; and when power having a phase difference of 180° is supplied to the first and second antenna units, radiation patterns of the first and second antenna units are in opposite directions along the first axis.

9 . The electronic device of claim 1 , wherein:
the first and second antenna units are arranged along a first axis; and when power having the same phase is supplied to the first and second antenna units, radiation patterns of the first and second antenna units are in a same direction perpendicular to the first axis.

10 . The electronic device of claim 1 , wherein power having a phase difference of 180° is supplied to the pair of feeding portions.

11 . The electronic device of claim 1 , wherein the first and second antenna devices are configured to radiate in a same direction or in opposite directions based on a phase difference of power supplied to the first and second antenna units.

12 . The electronic device of claim 11 , wherein the first and second antenna devices are configured to radiate in the same direction as the phase difference is near zero.

13 . The electronic device of claim 11 , wherein:
the first and second antenna devices are disposed at a first side of the electronic device; and the first and second antenna devices are configured to radiate in the same direction extending outwardly from the first side when power having the same phase is supplied to the first and second antenna units.

14 . The electronic device of claim 11 , wherein:
the first and second antenna devices are disposed at a first side of the electronic device; the first and second antenna devices are configured to radiate in the opposite directions respectively extending outwardly from a second side and a third side of the electronic device when power having a phase difference of 180° is supplied to the first and second antenna units; and the second side and third side are adjacent to the first side.

15 . The electronic device of claim 14 , wherein the first side corresponds to a top or bottom side of the electronic device and the second and third sides correspond to lateral sides of the electronic device.
