Abstract
A near field communication antenna included in a mobile device includes a body case and a loop antenna. The body case accommodates semiconductor devices included in the mobile device, and includes a metal material. The loop antenna is electrically connected to the body case. The loop antenna and a first portion of the body case form a signal path to perform a near field communication.
Claims12
A near field communication antenna included in a mobile device, the near field communication antenna comprising:
- a body case comprising a metal material and accommodating semiconductor devices included in the mobile device, the body case comprising a frame that forms a sidewall of the mobile device;
- and
- a loop antenna electrically connected to the body case, the loop antenna and a first portion of the body case being configured to form a signal path to perform a near field communication,
- wherein a second portion of the body case operates as an antenna to perform a non-near field communication,
- wherein the body case further comprises:
- a first metal structure that constitutes the second portion of the body case;
- a second metal structure;
- and
- insulating regions between the first metal structure and the second metal structure, the insulating regions electrically insulating the first metal structure and the second metal structure, and
- wherein the first metal structure and the insulating regions are disposed on a shorter sidewall of the frame.
