Data communication device

摘要

A communication device as disclosed herein may include a body, an antenna assembly provided in the body, and configured to transmit or receive wireless signals, and a circuit board connected to the antenna assembly and configured to process the wireless signals. The antenna assembly may include a carrier having at least one region that is dimensioned to be farther away from the body than other portions thereof, and a radiator provided on the at least one dimensioned region of the carrier and configured to receive or radiate electromagnetic waves corresponding to the wireless signals. The radiator may be positioned on the dimensioned region of the carrier such that a specific absorption rate (SAR) due to the antenna assembly is reduced.

1. A data communication device comprising:
a body; an antenna assembly provided in the body, and configured to transmit or receive wireless signals; a circuit board connected to the antenna assembly and configured to process the wireless signals, a data interface provided on the body, and an auxiliary antenna assembly disposed adjacent to the data interface, wherein the antenna assembly includes
a carrier having a first surface facing a front surface of the body, a second surface facing a side surface of the body, and recessed surfaces provided between the first and second surfaces of the carrier that are recessed to be farther away from the body than the first surface and the second surface of the carrier, anda radiator provided on the recessed surfaces of the carrier wherein the recessed surfaces include
a first recessed surface positioned adjacent to the first surface of the carrier and perpendicular to the first surface of the carrier, and a second recessed surface positioned adjacent to the first recessed surface and the second surface of the carrier and inclined at a prescribed angle relative to the second surface of the carrier and is stepped from the first surface and forms a stepped portion along a length of the first recessed surface, wherein the antenna assembly further includes a ground conductor provided adjacent to the radiator and grounded to the circuit board, wherein the ground conductor has a first part and a second part that intersect with each other at a prescribed angle, the first and second parts being parallel to consecutive edges of the radiator, respectively, wherein the data interface is a data port positioned in a region of the body opposite to the antenna assembly, wherein a cover is rotatably mounted to the body to cover the data port, wherein a metal plate is provided on the circuit board to dissipate heat from the circuit board, and is electrically connected to the auxiliary antenna assembly to form a ground for the auxiliary antenna assembly, and wherein the auxiliary antenna assembly includes first and second patterns connected to each other and also connected to the circuit board via a power feeding connection portion and a ground connection portion, respectively.
