Antenna apparatus for portable terminal

摘要

An antenna apparatus for a portable terminal is provided. The portable terminal includes a printed circuit board (PCB) having a ground surface and RF components to process a wireless signal received through at least one antenna element. A housing forms an external appearance of the portable terminal, and has a non-conductive member with a plurality of metal fragments attached thereto. At least one of the metal fragments is electrically connected to the ground surface. The metal fragments may enhance the texture and durability of the housing. Preferably, the shapes, sizes and distances separating the metal fragments are designed to minimally impact, or improve, the antenna performance provided by the at least one antenna element.

1. A portable terminal comprising:
a printed circuit board (PCB) having a ground surface and RF components to process a wireless signal received through at least one antenna of the portable terminal; and a housing forming an external appearance of the portable terminal, having a non-conductive member with a plurality of metal fragments attached thereto, with at least some of the metal fragments being electrically isolated from one another and proximate the at least one antenna; wherein the at least one antenna is disposed on the PCB and is separated from the housing; and wherein at least one of the metal fragments is electrically connected to the ground surface so as to prevent static electricity while the plurality of metal fragments provide a reactance that shifts a resonance frequency of the at least one antenna.
