Abstract
Disclosed is a shield can which operates as an antenna for location determination while blocking electromagnetic waves by defining a shielding area and radiation areas which resonate in one or more frequency bands by forming a shielding pattern and a radiation pattern, and an electronic module comprising same. Here, the shield can comprises: a carrier, a shielding pattern plated on a portion of the surface of the carrier to form the shielding area; and a radiation pattern plated on a different portion of the surface of the carrier to form a plurality of radiation areas.

A shield can disposed on a printed circuit board and configured to cover electronic components mounted on the printed circuit board, the shield can comprising:
- a carrier having an open lower surface and formed with an accommodating space accommodating the electronic components;
- a shielding pattern plated on a portion of a surface of the carrier to form a shielding area;
- and
- radiation patterns plated on the other portions of the surface of the carrier to form a plurality of radiation areas,
- wherein each of the radiation patterns and the shielding pattern are disposed at distances, and
- wherein the carrier includes:
- a plurality of side surfaces extending downward from an edge of an upper surface thereof;
- and
- a plurality of stepped surfaces formed by opening some edge portions at which the plurality of side surfaces meet.
