Title:
ANTENNA DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/153132
Kind Code:
A1
Abstract:
The present invention enables the direction in which reception is possible to be expanded for an on-vehicle device at low cost and with high gain, without limiting the installation direction or installation position on a vehicle. An antenna device (10) comprises: a printed board (13) that includes a circuit for measuring a position on the basis of a positioning signal; and a dipole antenna element (11) that is disposed on the printed board (13) and receives the positioning signal. The antenna device (10) also comprises a parasitic L-shaped antenna element (12), the dipole antenna element (11) and a long-side element (12) of the parasitic L-shaped antenna element are disposed at positions that are side-by-side but not in parallel, and an end section of a short-side element of the L-shaped antenna element (12) is disposed so as to be positioned near an end section of the dipole antenna element (11).
