Abstract
The present invention relates to an antenna device comprising a dielectric substrate (11;61) having at least one electrically conductive layer, a feeding (19) and a grounding (18) point. The antenna device is provided with a slot (14;71;81;91) having a closed path between an outer conductive region (12) and an inner (13) conductive region and is further provided with a feed slot (17;41;82;92;104) arranged at a first side of said closed slot (14;71;81;91), extending from said closed slot and outwards. A feeding means (2) is arranged to be connected to said feeding point (19) provided on said outer electrically conductive region (12) on a first side (15;16;73) of said feed slot (17;41;82;92;104), and a grounding means (3) is arranged to be connected to said ground point 18 provided on said outer electrically conductive region (12) on a second side, opposite to said first side, of said feed slot (17;41;82;92;104). The present invention also relates to an antenna assembly (110,120,130).
