Abstract: The present disclosure relates to an antenna element comprising a lower conducting plane, an upper conducting plane and an upper dielectric layer structure that is positioned between the conducting planes. The upper dielectric layer structure comprises a plurality of conducting vias that electrically connect the conducting planes to each other and circumvent an upper radiating patch formed in, below or above the upper conducting plane. The conducting vias circumvent at least one intermediate radiating patch that is formed in the upper dielectric layer structure, and a lowest intermediate radiating patch that is closest to the lower conducting plane is connected to a feed arrangement that comprises at least one feeding probe that extends via a corresponding aperture in the lower conducting plane and is electrically connected to the lowest intermediate radiating patch.

Abstract: The present disclosure relates to an antenna element (1) comprising a lower conducting plane (2), an upper conducting plane (3) and an upper dielectric layer structure (4) that is positioned between the conducting planes (2, 3). The upper dielectric layer structure (4) comprises a plurality of conducting vias (5) that electrically connect the conducting planes (2, 3) to each other and circumvent an upper radiating patch (6) formed in, below or above the upper conducting plane (3). The conducting vias (5) circumvent at least one intermediate radiating patch (7, 8) that is formed in the upper dielectric layer structure (4), and a lowest intermediate radiating patch (7) that is closest to the lower conducting plane (2) is connected to a feed arrangement (9, 10) that comprises at least one feeding probe (9, 10) that extends via a corresponding aperture (13) in the lower conducting plane (2) and is electrically connected to the lowest intermediate radiating patch (7).

Abstract: Antenna unit (16) comprising a flexible or bendable printed circuit board, PCB, (17), being divided into a number of sections (11), each section (11) being delimitated from another section (11) by a straight folding line (23). At least one section (11) accommodates an antenna element (10), and at least another adjacent section (11) is either accommodating an antenna element (10) having a terminal area (15) or is a terminal area (15). The antenna element is coupling to the terminal area (15) for feeding the antenna element (10), the adjacent sections (11) of the PCB being folded along the corresponding delimitating folding line (23) and being kept in or keeping a fixed position, such that the adjacent sections (11) are arranged at respective angles while each section (11) is maintaining a substantially plane configuration.

Abstract: The present disclosure relates to a planar antenna structure (100, 200, 800, 900) comprising at least one radiating aperture (101, 201 801, 901), adapted for a certain working frequency band, and an electrically conducting surface structure (102, 202, 802, 902) that is constituted by at least one surface part and is surrounding at least one radiating aperture (101, 201, 801, 901) and having a certain extension (T). The planar antenna structure (100, 200, 800, 900) comprises at least one continuous groove (103, 104; 203, 204; 803, 804; 903, 904) that forms a slot in the surface structure (102, 202, 802, 902), where each groove (103, 104) is defined by an at least virtual electric wall that is electrically connected to the surface structure (102, 202, 802, 902) and forms a continuous electromagnetic wall in the surface structure (102, 202, 802, 902) at the working frequency band. In this manner, that propagation of surface waves via the at least one groove (103, 104; 203, 204; 803, 804; 903, 904) is reduced.
