Abstract
Provided are an antenna device, a method of manufacturing the same, and an electronic apparatus having the antenna device. The antenna device includes: an insulating substrate; a first antenna pattern formed on one surface of the insulating substrate; and a second antenna pattern formed on the other surface of the insulating substrate and connected to the first antenna pattern.
Claims7
An antenna device comprising:
- an insulating substrate;
- a first helical antenna pattern formed on one surface of the insulating substrate, the first helical antenna pattern being formed of a first conductive thin film and having a first start end placed inner side of the first helical antenna pattern and a first terminal end protruding from the first helical antenna pattern;
- and
- a second helical antenna pattern formed on the other surface of the insulating substrate the second helical antenna pattern being formed of a second conductive thin film and having a second start end placed inner side of the second helical antenna pattern and a second terminal end protruding from the second helical pattern,
- wherein the first start end and the second start end are connected to each other by a conductive member through a via hole formed in the insulating substrate so that the first helical antenna pattern and the second helical antenna pattern form a single antenna pattern, and the first terminal end and the second terminal end function as a terminal of the single antenna pattern to input and output a wireless power signal, and
- wherein the first helical antenna pattern and the second helical antenna pattern have a same thickness.

A method of manufacturing an antenna device, the method comprising:
- forming an insulating substrate;
- forming a first conductive thin film on one surface of the insulating substrate;
- forming a second conductive thin film on the other surface of the insulating substrate, wherein the first conductive thin film and the second conductive thin film have a same thickness;
- forming a mask pattern on the first conductive thin film and the second conductive thin film;
- simultaneously wet-etching the first conductive thin film and the second conductive thin film to form a first helical antenna pattern having a first start end placed inner side of the first helical antenna pattern and a first terminal end protruding from the first helical antenna pattern, and a second helical antenna pattern having a second start end placed inner side of the second helical antenna pattern and a second terminal end protruding from the second helical pattern;
- removing the mask pattern;
- and
- connecting the first start end and the second start end for the first helical antenna pattern and the second helical antenna pattern to form a single antenna pattern.
