ABSTRACT:
An antenna apparatus for a portable terminal includes an antenna device contained in a housing of the terminal and a coaxial cable for connecting the antenna device to circuitry of the terminal. The coaxial cable connects a power feed and a ground of the antenna device to a power feed and a ground of the circuitry, respectively. The antenna apparatus for a portable terminal is advantageous in that, since the coaxial cable supplies power to the antenna device, which is spaced apart from the RF circuitry, and grounds are provided to the circuitry, which includes the RF circuitry, and to the antenna device, respectively, the connection properties and antenna characteristics are stable. Thus, even when an additional component (such as a camera module) is installed and the circuit configuration is changed, the antenna device, which is positioned on the upper end of the terminal, still exhibits optimal radiation performance.
