Miniaturized 3D-printed Antenna Realizations for Cylindrical Surface Mounting

In this paper two types of miniaturized 3D-printed, waveguide antennas been designed, simulated and measured. Several pieces of antennas have been manufactured to investigate the impact of dimensions inaccuracy of 3D-printing technology on return loss parameter. In order to reduce the impact of dimensions spread and differences in a printed material permittivity a tuning process in a dielectric-filled antenna is proposed.
