ANTENNA ARRANGEMENTS AND MICROWAVE DEVICES WITH IMPROVED ATTACHMENT MEANS

摘要

An antenna arrangement (100) having a stacked layered structure. The antenna arrangement comprising a radiation layer (110) comprising one or more radiation elements (111), and a distribution layer (120) facing the radiation layer (110). The distribution layer (120) is arranged to distribute a radio frequency signal to the one or more radiation elements (111). The distribution layer (120) comprises at least one distribution layer feed (224). Any of the distribution layer (120) and the radiation layer (110) comprises a first electromagnetic bandgap, EBG, structure (121) arranged to form at least one first waveguide intermediate the distribution layer (120) and the radiation layer (110). The first EBG structure is also arranged to prevent electromagnetic radiation in a frequency band of operation from propagating from the at least one first waveguide in directions other than through the at least one distribution layer feed (224) and the one or more radiation elements (111). The radiation layer (110) and the distribution layer (120) are attached to each other with one or more fastening members (101) comprising respective deformable tails (102).
