N2 - Recently, we proposed a 360° beam-steerable antenna with frequency reconfigurability. This antenna com-bines design techniques and technologies from microwave to optics, including a broadband antenna, metasurface-inspired tunable resonators, two Vivaldi-shaped PCB plates, and a 3D printed dielectric toroidal lens. Benefiting from its tuning mechanism, the antenna can support either directional or omnidirectional modes. The proposed antenna is able to steer its beam azimuthally with an angular resolution of 18°, horizontal polarization and realized gains from 6.2-8.2 dBi over a tunable frequency range from 2.2 to 2.4 GHz. In this work, we further analyze the design of the 3D printed toroidal lens with investigations on various lens profiles. Additionally, the azimuthal beamwidth reconfigurability is explored by varying the configuration of the beam controller. The presented studies demonstrate enhanced performance and broadened application range for this reconfigurable antenna.
