Abstract
An antenna element () for an array antenna. The antenna element having a layered configuration comprising a first ground plane (), a first dielectric layer () facing the first ground plane (), a first planar radiation element () facing the first dielectric layer (), and a feeding via hole () arranged electrically connected to the first planar radiation element () and arranged extending through the first dielectric layer () and through the first ground plane () without electrical contact. The antenna element further comprises at least one complementary set comprising a complementary dielectric layer () and a complementary planar radiation element () facing the complementary dielectric layer. The set is arranged stackable facing the first planar radiation element () such that a complementary dielectric layer is arranged between two radiation elements () in the layered configuration. The first planar radiation element () constitutes a first continuous part of a spiral antenna and the at least one complementary planar radiation element () constitutes a continuation of the spiral antenna, thereby the first and the at least one complementary planar radiation elements () constitute an effective spiral antenna.
