PURPOSE:To directly pick up an antenna output with small size, by mounting a battery power supply for amplification circuits on a printed circuit board on which each element of an antenna device is formed incorporatedly. CONSTITUTION:A battery power supply E' for an amplifying circuit AMP is given through the mounting on a printed wiring board 1a to an antenna device 10 consisting incorporatedly of an antenna main body ANT and the AMP. In this case, the battery E' is mounted between a pair of battery terminals P3 and P4 and between holders H1 and H2 disposed to a battery terminal connection pattern 11 and holder fitting holes 13 and 14 of the printed board 1a, and as the circuit, the plus terminal of the battery is connected to one end of a choke coil RFC1 via a switch SW'. |
