<P>PROBLEM TO BE SOLVED: To solve the problem that, since a conventional multiband equivalent antenna is configured in such a way that each of a plurality of antenna elements deals with each frequency, when the antenna trying to deal with much more frequencies, the number of antenna elements is increased necessarily and since a length of each antenna element is corresponding to each frequency, when the number of antenna elements is increased, the size of the overall antenna is enlarged, thereby material costs for manufacturing the antenna are increased. <P>SOLUTION: An antenna apparatus includes a plurality of antenna elements and a feeding point provided in any one of the plurality of antenna elements. The plurality of antenna elements are connected at one or more points with each other, partially have areas proximate to each other, are coupled in the proximate area at a specific resonant frequency to form a resonance loop and further have a plurality of proximate areas. <P>COPYRIGHT: (C)2010,JPO&INPIT |
