1. An antenna apparatus comprising:
- a base;
a plurality of feeding-radiating elements each including a feeding electrode and a radiating electrode which are disposed on the base; and
a substrate arranged to support the base;
wherein a common feeding point for feeding a current to the plurality of feeding-radiating elements is located on the substrate;
a stub continuously expanding from the common feeding point is disposed on a surface of the substrate, or on a surface of the base and a surface of the substrate; and
the feeding electrodes of the plurality of feeding-radiating elements are connected to matching points of the stub which are determined based on the effective line length of the radiating electrodes.

Abstract
An antenna apparatus includes a dielectric base, and a plurality of feeding-radiating elements having different resonance frequencies, each including a feeding electrode and a radiating electrode which are disposed on surfaces of the base. A stub with a common feeding point is disposed on a mounting substrate which supports the base. The feeding electrodes of the feeding-radiating elements are connected to matching points of the stub, thereby achieving impedance matching for each of the feeding-radiating elements.
