<P>PROBLEM TO BE SOLVED: To provide a tunable antenna obtaining a sufficient receiving sensibility and conducting a receiving with one output terminal. <P>SOLUTION: The tunable antenna has a first wave-receiving element 11 consisting of a metallic conductor and a first variable capacity means 21 electrically connected at one end section of the first wave-receiving element 11 and a second wave-receiving element 12 consisting of the metallic conductor and a second variable capacity means 22 electrically connected at one end section of the second wave-receiving element 12. The tunable antenna further has a high-frequency signal feed section 3 electrically connected at the other end section of the first wave-receiving element 11 and the other end section of the second wave-receiving element 12, a high-frequency signal output terminal 31 outputting high-frequency signals received respectively and a grounding terminal electrically connected to the high-frequency signal feed section 3 while being grounded. <P>COPYRIGHT: (C)2010,JPO&INPIT |
