WebApr 1, 2015 · A fully spherical dipole antenna with an internal source has been fabricated via 3D printing of conductive ink. By distributing the antenna onto the package of a small device rather than in a small PCB footprint, the antenna's bandwidth can more closely approach the fundamental limits. In this case, the antenna's bandwidth-efficiency product is ... WebJun 1, 2016 · The spherical near-field antenna measurement technique combines several advantages and generally constitutes the most accurate technique for experimental characterization of radiation from antennas.

WebIn contrast to earlier studies where each antenna beam is optimised, the use of multiple-beam spherical lens antennas leads to each beam of a given cluster having the same beamwidth and also having circular symmetry. Taking the layout of 121 cells shown in Fig. 3, where cells are arranged in 6 concentric hexagonal rings, we can specify an antenna
