E-Plane-Focused Partial Maxwell Fish-Eye Lens Antenna for Multibeam Wide-Angle Scanning

Alumina 3-D Printed Wide-Angle Partial Maxwell Fish-Eye Lens Antenna

“…3. The works in [12]- [13] suggest cutting the lens at the position of 0.45R in the bed-of-nails and dielectric filled PPW configurations, to achieve a maximum in beam-steering capabilities. However, such implementations are highly dispersive over frequency due to the use of metallic parts, which is in contrast to a low-dispersive dielectric unit cell design used in this work.…”

“…In our work, we focus on the partial Maxwell Fish-Eye lens (PMFE), which uses gradient permittivity profiles close to those of the Gutman and Eaton lens types, thus combining their functionality [12]- [13]. Other examples of multi-functional lenses are bifunctional Luneburg/Eaton, or Luneburg Petr Kaděra and Jaroslav Lacik are with the Department of Radio Electronics, Brno University of Technology, Technická 12, 612 00, Brno, Czech Republic (e-mail: kadera@vut.cz; lacik@vut.cz).…”

“…lenses, whose functionality is dependent on the electromagnetic (EM) wave propagation direction as discussed in [24]- [25]. The PMFE lenses presented in [12]- [13] are functionally limited to the azimuthal plane and their angular performance is strongly dependent on the dispersion characteristics of the used metallic structure geometry. Moreover, the practical realization of the wide-angle lenses operating in broadband frequency ranges and frequencies in the order of and over 100 GHz is often costly and highly demanding.…”
