Title:
ANTENNA DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/033722
Kind Code:
A1
Abstract:
An antenna device is provided with a plurality of antenna elements arranged in a row. The antenna elements located at both ends are each called an end-side antenna element, and the antenna element other than the end-side antenna elements is called an inside antenna element. The end-side antenna element has a structure different from that of the inside antenna element such that a difference in directivity between those used as feed elements among the antenna elements is reduced. Consequently, the estimation accuracy of an arrival direction is improved by a simple method without increasing the amount of calculation.
