Abstract
his paper introduces a beam-adjustable multibeam
dielectric rod antenna for mm-wave RF-WPT applications. The
unique multibeam setup allows the generation of several ad-
justable beams simultaneously. This is conceptualized by utilizing
three and five rods to create a beam coverage between −30◦ to 30◦
in the azimuth plane. In the proposed configuration, the peak gain
value of each generated beam is 13 dBi at 23.8 GHz. A gain value
above 12 dBi is maintained between 20 GHz and 24 GHz. The
Rexolite rod is fed through an annular slot fabricated on a Rogers
RO4003 substrate. The adjustable nature of this configuration
makes the solution agile, with the possibility of adaptation to
different scenarios either by altering the number of unit elements
employed or their orientation. This capability, together with the
low cost of the proposed solution, makes it a promising power
delivery solution for Internet of Things (IoT).
