| Zusammenfassung: | The simply configured substrate antenna has a plurality of antennas. A loop-like first joint pattern one spot of which is divided is formed in one-side substrate surface of a substrate composed of a dielectric material. Antenna elements that configure a first antenna are respectively connected to both ends of the first joint pattern at the divided position. A loop-like second joint pattern one spot of which is divided is formed in the other-side substrate surface at a position opposite to the first joint pattern. Antenna elements that configure a second antenna are respectively connected to both ends of the second joint pattern at the divided position. The first and second antennas are set to approximately the same or different resonance frequency bands. Feeding and ground points connected to and formed in the first joint pattern are held in common to transmit or receive a transmission/reception signal. |
