<p><P>PROBLEM TO BE SOLVED: To provide an antenna device that reduces mutual coupling between antennas in a space saving configuration. <P>SOLUTION: The antenna device includes: a circuit board body 2; a first antenna section 3A and a second antenna section 3B interspaced on a surface of the circuit board body 2; a ground plane GND formed on the surface of the circuit board body 2 and having an intermediate region GND1 and both side regions GND2; and a pair of coaxial cables 4 connecting a pair of antenna side feeding points FP1 disposed in the first antenna section 3A and second antenna section 3B to a pair of circuit side feeding points FP2 disposed in the intermediate region GND1. The coaxial cables 4 are routed from the antenna side feeding points FP1 to the circuit side feeding points FP2 disposed in the intermediate region so as to avoid passing directly over ground patterns 6 and pass directly over both side regions. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
