1. A loop antenna comprising:
- a radiator which is formed in a loop; and
a matching circuit, integrally formed with the loop antenna, which comprises an extension part which extends from one side of the radiator to an inner side of the loop and a bend part bent from an end of the extension part,wherein the matching circuit is disposed inside the radiator,wherein one side of the radiator is open, a first open end is a feed point, a second open end is a short point, and the extension part comprises a pair of extension lines which extend from an area opposite to the open one side.

Abstract
A loop antenna is provided having a matching circuit integrally formed includes a radiator which is formed in a loop shape; and a matching circuit including an extension part extended from one side of the radiator to an inner side of the loop and a bend part bent from an end of the extension part several times. Accordingly, the space for the installation of the loop antenna can be reduced and the design modification of the matching circuit can be facilitated.
