| 摘要 |
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. <IMAGE> |
