Abstract
There is provided a flat antenna apparatus in which a low-noise amplifier provided therein does not generate an abnormal oscillation, and a case and a ground pattern formed on a circuit board are reliably connected to each other by means of a simple construction. A flat antenna element is mounted on a circuit board. The circuit board has an amplifying circuit for amplifying a radio frequency received from the flat antenna element. A case and the flat antenna element are attached to opposite sides of the circuit board. A tab formed on a peripheral edge of the case is inserted into a slot formed on the circuit board, the tab being soldered to fix the case on the circuit board.
