PROBLEM TO BE SOLVED: To easily improve the antenna characteristics and miniaturize an antenna.;SOLUTION: A feed radiation electrode 2 and a non-feed radiation electrode 3 have main surfaces 2M, 3M with a space on a board surface 4a, respectively. The main surfaces 2M, 3M are adjacently laid in the horizontal direction with a space between them. Grounding electrodes 2G, 3G are formed to extend from the ends Egs of the main surfaces 2M, 3M at the shorting connection side. The grounding electrode 2G extends from the feed radiation electrode 2 to the non-feed radiation electrode 3 with the extending top end connected to a board at the electrode 3. The grounding electrode 3G extends from the non-feed radiation electrode 3 to the feed radiation electrode 2 with the extending top end connected to a board at the electrode 2. The grounding electrodes 2G, 3G have their electrode surfaces opposed to each other through a space.;COPYRIGHT: (C)2005,JPO&NCIPI
