Abstract (en)
[origin: EP0325702A1] A miniaturised stripline antenna (group antenna) having - an electrically conductive baseplate (a> - an electrically insulating substrate (b> - a group of radiating elements (c) and - supply lines (d), the distance between the baseplate (a) and the radiating elements (c) being enlarged by means of mesa-shaped raised areas or by trough-shaped depressions. <IMAGE>
