ANTENNA FOR MOBILE OBJECT COMMUNICATION

PURPOSE:To connect a patch antenna element layer and a circuit pattern layer without the need for using a feeding pin and also, without executing soldering. CONSTITUTION:An antenna base body is formed by a multilayer laminated plate 7 in which a patch antenna element layer 11 and a circuit pattern layer 10 are laminated on one surface and the other surface, respectively, and also, an earth pattern layer 4 is laminated between the patch antenna element layer 11 and the circuit pattern layer 10. In the part of a pass hole 15 provided on the earth pattern layer 4, a through-hole 13 extending from the patch antenna element layer 11 to the circuit pattern layer 10 is provided on the multilayer laminated plate 7. In the inner periphery of the throughhole 13, a throughhole plating layer 14 is provided and by the throughhole plating layer 14, the patch antenna element layer 11 and the circuit pattern layer 10 are subjected to conducting connection.
