Multi-Beam Geodesic Lens Antenna with Enhanced Aggregate Gain in the Ka-band

Abstract

New mobile generations, i.e. 5G and 6G, will operate in the millimeter-wave band to support higher data rates. Novel antenna technologies must be investigated to mitigate the higher losses in this frequency band. One promising technology for this specific application is geodesic lens antennas. Here, we propose an analytical model that calculates the far-field distribution of a geodesic lens. This model was used to design a multibeam 9-port geodesic lens with a widened radiation pattern. A coverage sector of 134° in the H-plane is achieved with a gain roll-off better than 3 dB at 28 GHz.
