Antenna apparatus |
摘要 |
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.
