Abstract
There is disclosed a mobile terminal including a case, a first antenna mounted in the case to perform wireless communication in a specific frequency band, a grounding surface mounted in the case, a receiver mounted in the case, toward a front surface of the case, a battery cover coupled to a rear surface of the case, the battery cover comprising a conductive portion, and a contact pin configured to connect the conductive portion and the grounding surface with each other, wherein the contact pin is formed in a predetermined portion where a phase of an electromagnetic field formed by the first antenna changes. The mobile terminal may adjust the HAC grade to a base grade or higher of the HAC by adjusting the position of the electromagnetic field peak, regardless of the size of the mobile terminal.
Claims16
A mobile terminal comprising:
- a case;
- a first antenna mounted at a lower end portion of the case to perform wireless communication in a prescribed frequency band;
- at least one second antenna corner of upper end portion of the case,
- a grounding surface mounted in the case;
- a receiver mounted in the case, toward a front surface of the case;
- a battery cover coupled to a rear surface of the case, the battery cover including a conductive portion;
- and
- a contact pin configured to connect the conductive portion and the grounding surface with each other,
- wherein a center of the conductive portion is extended toward each right and left portion such that the conductive portion has a cross shape,
- wherein the contact pin is movable and is connected to the extended portion of the conductive portion and the grounding surface where a phase of an electromagnetic field formed by the first antenna changes, and
- wherein the contact pin is positioned a prescribed distance to the first antenna, and the prescribed distance between the contact pin and the first antenna corresponds to a distance where a magnitude of the electromagnetic field formed by the first antenna is below a prescribed minimum level.
