Abstract

Provided are an antenna and a mobile terminal including the antenna. The antenna includes a loop antenna, a solenoid, and a plurality of connections. The loop antenna is installed on a mobile terminal. The solenoid is connected in parallel to the loop antenna, and receives power. The connections connect the loop antenna to the solenoid. Accordingly, the degree of freedom of an antenna shape and a recognition distance of the antenna are improved.

Claims

1. An antenna comprising:

a loop antenna installed on a mobile terminal;

a solenoid connected in parallel to the loop antenna, and receiving power; and

a plurality of connections connecting the loop antenna to the solenoid.

2. The antenna according to claim 1, wherein the loop antenna comprises one or more square patterns, and

the solenoid is disposed inside of the square patterns.

3. The antenna according to claim 2, wherein the connections connect the outermost one of the square patterns to terminals of the solenoid, and comprise two contacts that are symmetrical to each other with respect to an inner center of the loop antenna.

4. The antenna according to claim 3, wherein the connections comprise a plurality of contacts connecting a portion of the solenoid to the square pattern disposed inside of the outermost square pattern.

5. A mobile terminal comprising the antenna according to claim 1.

6. A mobile terminal comprising the antenna according to claim 2.

7. A mobile terminal comprising the antenna according to claim 3.

8. A mobile terminal comprising the antenna according to claim 4.
