<p>An antenna apparatus is provided with: a chip antenna (101) including a dielectric block and a radiating electrode formed on the dielectric block; and a substrate (201) including a base material and a ground conductor formed on the base material. The radiating electrode of the chip antenna (101) has a first end grounded to the ground conductor and is capacitively fed via a second end. A slit (SL) is formed in an area opposite the mounting surface of the chip antenna (101). In this configuration, an electric field leaks via the slit, whereby the amount of current induced in the ground conductor of the substrate is increased, and the amount of radiation from the ground conductor is increased. Further, the inverse phase current (ECr) that would flow into the ground conductor of the substrate is suppressed by the slit.</p> |
