Antenna apparatus and mobile communication apparatus using the same
First Claim
1. An antenna apparatus comprising a chip antenna and a mounting substrate on which said chip antenna is mounted, said chip antenna including a base member made from ceramic, a conductor formed on said base member, and a power-supply electrode to which one end of said conductor is connected and a terminal electrode to which the other end of said conductor is connected, both formed on a surface of said base member, and said mounting substrate including a radiative conductor and a ground electrode, wherein the terminal electrode of said chip antenna is connected to one end of the radiative conductor of said mounting substrate, said radiative conductor being disposed so as to be asymmetrically connected with respect to the conductor of the chip antenna near one end of the radiative conductor to the conductor of the chip antenna as viewed in a direction perpendicular to a plane in which the mounting substrate is disposed.

Abstract
An antenna apparatus 10 includes a chip antenna 14 provided with a conductor 11, a power-supply electrode 12 to which one end of the conductor 11 is connected, and a terminal electrode 13 to which the other end of the conductor is connected; and a mounting substrate 18 provided with a line-shaped radiative conductor 15 formed by printing an electrically conductive material on a surface, a line-shaped conductive pattern 16, and a substantially rectangular ground electrode 17. The chip antenna 14 is mounted on the mounting substrate 18. The power-supply electrode 12 of the chip antenna 14 is connected through the conductive pattern 16 on the mounting substrate 18 to a power-supply source V. The terminal electrode 13 of the chip antenna 14 is connected to one end of the radiative conductor 15 on the mounting substrate 18.
