<p>The antenna comprises a first substrate (2) with a conducting layer in a layout plan (3) and another conducting layer (4) and a second substrate (5) comprising a conducting layer (6), arranged on the first substrate. Several substrates made from dielectric foam may be simply stacked such that the conducting layers (4, 6) thereof alternatively comprise one or two projections (21) and an opening (61) which comprises radiating elements which contribute to widening the frequency band of the antenna.</p> |
