Antenna arrangements and microwave devices with improved attachment means

Abstract

To provide antenna arrangements with high manufacturing yields and high performance.SOLUTION: An antenna arrangement 100 includes a radiation layer 110 including one or more radiation elements 111, and a distribution layer 120 facing the radiation layer 110. The distribution layer 120 includes at least one distribution layer feed. Either the distribution layer 120 or the radiation layer 110 includes a first electromagnetic bandgap structure 121 to form at least one first waveguide between the distribution layer 120 and the radiation layer 110. The first EBG structure prevents 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 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 including respective deformable tails 102.SELECTED DRAWING: Figure 1A
