Abstract

PURPOSE:To obtain an antenna device which can receive waves over a wide band efficiently, by connecting an amplifying element of high input impedance to a sectorial reception antenna element. CONSTITUTION:Sectorial antenna elements 1 and 2 are formed on a flat plate by coating a conductor layer such as copper on a plastic base 4 by printing. A signal received on the antenna elements 1 and 2 is applied to a drain terminal D of MOSFETs 11 and 12 showing high impedance characteristics via coupling capacitors 27 and 28 and a balun 22. The MOSFETs 11 and 12 are operated as a common-base amplifier, and a reception signal obtained at the source terminal S is applied to loads 13 and 14. Thus, the broad band and high gain of the sectorial antennas can be realized by connecting the high input impedance element to the sectorial antenna elements.
