| 20110309989 | Substrate Type Antenna - The present invention provides a substrate type antenna capable of realizing high gain enhancement and high band enhancement in a simple configuration. In the substrate type antenna, a loop-like first joint pattern whose one spot is divided, is formed in one substrate surface of a substrate made of a dielectric material. Antennas are 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 formed at a position corresponding to the first joint pattern and whose one spot is divided, is formed in the other substrate surface of the substrate. A loop-like third joint pattern which is substantially concentric with the first joint pattern and which is formed at a position corresponding to the second joint pattern and whose spot is divided, is formed in the one substrate surface of the substrate. Other antennas are respectively connected to both end terminals of the third joint pattern at a position where the third joint pattern is divided. | 12-22-2011 |
