<P>PROBLEM TO BE SOLVED: To provide an antenna apparatus which is made to have a low profile and induces a plurality of resonances of high input impedance. <P>SOLUTION: The antenna apparatus includes a short-circuit path having its front end connected to a ground point disposed nearby a feed point, a first chip-open element extended from a back end of the short-circuit path and having its back end made open, a feed side part element extended from nearby the feed point in the extension direction of the first chip-open element so that one side thereof is close to a ground surface, a second chip-open element extended from nearby a back end of the feed side part element in the extension direction of the first chip-open element and having its back end made open, and a short-circuit element connecting one point on one side of the feed side part element opposed to a side nearby the ground surface or one point on the second chip-open element and the front end of the first chip-open element to each other. <P>COPYRIGHT: (C)2010,JPO&INPIT |
