ARRAY ANTENNA DEVICE

摘要

An array antenna device is equipped with a first substrate (100) provided with a first feeding point (F1) and a second substrate (200) provided with a second feeding point (F2). The first substrate (100) is provided with multiple first radiation elements (101) and a first feeding line (201), the first feeding line connecting the first feeding point (F1) and the respective multiple first radiation elements (101) in an equal-length pattern wiring so that the multiple first radiation elements (101) form linearly-polarized waves in a first polarization direction. The second substrate (200) is provided with multiple second radiation elements (102) and a second feeding line (202). The multiple second radiation elements are opposite to the multiple first radiation elements (101) respectively. The second feeding line (202) connects the second feeding point (F2) and the respective multiple second radiation elements (102) in the same equal-length pattern wiring as the first feeding line (201) so that the multiple second radiation elements (102) form linearly-polarized waves in a second polarization direction that is orthogonal to the first polarization direction.
