Abstract (en)

For increased bandwidth an electromagnetically coupled microstrip antenna device comprises a first substrate 1; an antenna element 2 provided on a first surface 1a of the first substrate 1; a second substrate 2; and a feeding element 4 provided between a second surface 1b of the first substrate 1 and a first surface 3a of the second substrate 3; wherein an end portion 4a of the feeding element 4 is positioned within a range of -0,3L and +0,3L from an edge portion 2a of the antenna element 2, wherein L is the extension of the antenna element 2 in the of overlap between the antenna element 2 and the feeding element 4. <IMAGE>
