    Abstract: An antenna arrangement for a Multiple Input Multiple Output (MIMO) radio system, the antenna arrangement transmitting and receiving in three essentially uncorrelated polarizations. The arrangement includes three parallel, stacked patches separated by first and second slots. A first feeding line feeds the first patch, and at least a second and third feeding line feed the second patch. In a first operating mode, the first feeding line generates a first constant E-field in the first slot between the edges of the first and second patches. In a second operating mode, the second feeding line contributes to a second, sinusoidally varying E-field in the second slot between the edges of the second and third patches. In a third operating mode, the third feeding line contributes to a third, sinusoidally varying E-field in the second slot between the edges of the second and third patches.

    Abstract: The present invention relates to an antenna arrangement comprising a dielectric medium (2) with a first side (3) and a second side (4), with a feeding arrangement (6; 6') on the first side and at least one slot (5; 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73) in a ground plane on the second side, where the feeding arrangement comprises at least a first (13; 13'; 37; 37'), a second (14; 14'; 38; 38'), a third (15; 15'; 41; 41') and a fourth (16; 16', 42; 42') feeding conductor, each intersecting the gap of the slot (5; 62, 63, 64, 65; 66, 67, 68, 69, 70, 71, 72, 73), where each intersection constitute a feeding point (17, 18, 19, 20; 39, 40, 43, 44, 50, 51, 52, 53) for the antenna arrangement (1; 1'; 1''; 1'''). In a first mode of operation, a first constant E-field (26) that is directed across the slot is obtained. In a second mode of operation, a second E-field (28) which is directed across the slot, having a sinusoidal variation is obtained. In a third mode of operation, a third E-field (30) which is directed across the slot, having a sinusoidal variation, is obtained.

    Abstract: A method (20) performed in a network node (4) is provided for alerting about failure of an unmanned aerial vehicle (2). The method (20) comprises receiving (21) a failure report from an unmanned aerial vehicle (2), obtaining (22) an estimated crash point for the unmanned aerial vehicle (2), and sending (23), based on the obtained estimated crash point, warning signals to communication devices (3) residing within a defined area. Methods in an unmanned aerial vehicle and in a network entity, and a network node, unmanned aerial vehicle, network entity, computer programs and computer program products are also provided.
