Abstract

PURPOSE:To use this antenna for both of weak and strong electric field with small size, by incorporatedly forming two types of antennas ad tuning circuits on a printed circuit board. CONSTITUTION:Back side of a both side printed circuit board 1a is provided with the 1st antenna conductor 2, connection conductors 3, 4, and 5, 6 and a pattern 7 for amplifying circuit incorporatedly. The front side of the board 1a is simultaneously incorporated with the 2nd antenna conductor 11 having an open end partly at the external circumference, a pair of connection conductors 12 and 13 extended from the open end of the 2nd antenna conductor 11 toward the inside, and a pair of connection conductors 14 and 15 extended from the position being the feeding point of opposite side to the open end of the 2nd antenna conductor 11 toward inside, with the photoetching technology. One of a twin tuning variable capacitor VC' is connected to the 1st antenna conductor and another is to the 2nd antenna conductor.
