ANTENNA

PURPOSE:To obtain an antenna whose assembling is facilitated by opposing a radiation electrode or a radiation plate of an antenna unit to a feeding electrode of an insulation board so as to integrate the antenna unit and a printed circuit board. CONSTITUTION:A radiation electrode 2 is formed on the surface of a dielectric body 1, a ground electrode 3 is formed to a rear side to form an antenna unit 4. An electrode pattern 5a is formed to one side of a board 5 make of a glass epoxy board, and an electronic circuit 6 comprising plural electronic components is mounted on the pattern 5a. Furthermore, a feeding electrode 5 connecting to an electrode pattern 5b being an input section of the circuit 6 via a throughhole 5c and a ground electrode 5e insulated from the electrode 5d are formed to the other side to form a printed circuit board 7. The ground electrode 3 of the antenna unit 4 and a ground electrode 5e of the board 7 are soldered to form an antenna 8 by integrating the antenna unit 4 and the board 7.
