Patent number: 9843101Abstract: Antenna system for a georadar, comprising two plate like antenna devices, where said two antenna devices comprise at least one sender antenna (1) and at least one receiver antenna (2), respectively, as the antennas (1,2) in each antenna device comprise monopoles formed by applying to metal surfaces an electrically insulating plate base (3) located on the underside of a layer of radar absorbing material (4), where the top side of the material layer is covered by a metallic ground plane (5). The antenna device is also arranged to lay against the ground (10). A layer of radar absorbent material (4) is arranged on the top side of the ground planes (5), and the ground planes (5) are not connected electrically to each other.Type: GrantFiled: January 9, 2015Date of Patent: December 12, 2017Assignee: 3D-RADAR ASInventor: Egil Eide
