<P>PROBLEM TO BE SOLVED: To provide an antenna sharing two frequencies, equipped with a low-frequency band element and a high-frequency band element so as to easily adjust each frequency band, and which is capable of being reduced in size while reducing mutual interference. <P>SOLUTION: The antenna 100 is branched into the low-frequency band element 110 and the high-frequency band element 120 by sharing a circuit connection part 101. Each of the elements is returned at return parts 111, 121 so as to make their opening ends 112, 122 close. A separation part 113, in which a center part of the low-frequency band element 110 is arranged in a non-contact manner, is formed between the two opening ends 112, 122. <P>COPYRIGHT: (C)2009,JPO&INPIT |
