3D Printed Modulated Geodesic Lens Antenna With Even Coverage in the Far-Field

Sammanfattning: The development of 5G and 6G entails new demandson antennas. This includes fast and reliable connections to a largenumber of devices. A wider area of coverage, and thus moreantennas are also expected, which is problematic for the expensiveantennas used today. To meet those demands, a geodesic lensantenna has been proposed. The antenna utilises several feedingports for beam forming. It is designed to operate at a frequencyof 8 to 12 GHz and is optimised to have an even coverage in thefar-field. The design is modulated with one fold to reduce theheight of the antenna. A prototype of the antenna is 3D printedwith PLA and coated with aluminium tape. The design has asimulated realised gain of 13.5 dBi and beam width of around30°. The 3D printed antenna could not be tested due to technicalproblems with the testing facilities, but is expected to have similarresults.
