Patent ID: 8681069

Claim:
A substrate type antenna comprising: a loop-like first joint pattern one spot of which is divided, said first joint pattern being formed in one substrate surface of a substrate comprised of a dielectric material; antennas respectively connected to both end terminals of the first joint pattern at a position where the first joint pattern is divided; a loop-like second joint pattern which is formed at a position opposite to the first joint pattern and has feeding points, and one spot of which is divided, said second joint pattern being formed in a backside substrate surface of the substrate; at least another loop-like joint pattern one spot of which is divided, said loop-like joint pattern being formed at a position opposite to the second joint pattern; and other antennas respectively connected to both end terminals of said another joint pattern at a position where said another joint pattern is divided, wherein the antennas connected to the first joint pattern and said other antennas connected to said another joint pattern are made different in resonant frequency.
