Abstract

PURPOSE:To make the size small, by incorporatedly forming antenna conductors having different antenna gains and tuning circuits directly connected to the antenna conductors on a multilayered printed circuit board. CONSTITUTION:The 1st antenna device 10a consisting of an antenna main body and an amplifying circuit AMP formed incorporatedly on a printed circuit board 1. Under the 1st antenna device 10a, another printed circuit board 1 of similar constitution except the omission of a tuning variable capacitor VC and the AMP from the device 10a is mounted via a spacer 16 as two-layered construction. The connection conductors of the printed board mounted at the lower side are connected to the variable capacitor VC of the 1st antenna device 10a via leads 17 and 18 and the 2nd antenna device 10a is constituted with the antenna conductor 2 of said printed board 1.
