ON-VEHICLE ANTENNA DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an on-vehicle antenna device which enables easy installation work without restricting the installation position, maintains good antenna characteristics while improving visibility when used in a windshield, and improves the work efficiency of the installation work.

SOLUTION: An antenna device body 20 includes: an antenna lower housing 11 and an antenna upper housing 12 which have long plate like shapes and engage with each other; a circuit board 15 which is disposed on the substantially center part of the antenna lower housing 11; and a GND side antenna element 16 and a power supply side antenna element 17 that are disposed at the antenna lower housing 11 and connect with the circuit board 15. The antenna lower housing 11 is composed of: a first section having a circuit board installation part 110 and forming a rigid body; and a second section located adjacent to the first section relative to the longitudinal direction of the antenna lower housing 11 and forming an elastic body.
