Abstract

An antenna element (1) is provided, comprising a patch antenna (2) extending in a main plane (P1), a conductive structure (3), a first feed line (6a), and a second feed line (6b). The conductive structure (2) includes a bottom element (7) and at least one wall element (4), the wall element (4) at least partially surrounding an aperture (5), and the patch antenna (2) is superimposed on the aperture (5). The first feed line (6a) and the second feed line (6b) extend from the bottom element (7) through the aperture (5) and are coupled to the patch antenna (2). The aperture (5) can be used to generate a first resonant frequency (F1) and a fourth resonant frequency (F4), and the patch antenna (2) is used to generate a second resonant frequency (F2) and a third resonant frequency (F3), wherein (F1)>(F2)>(F3)>(F4). The patch antenna (2), the conductive structure (3), the second via (10), the dielectric gap (11), and / or the recess (12) are used to extend the bandwidth of one or more of the resonant frequencies.
