Abstract：

We　propose　a　mechanically-controlled,　onedimensional　wide-angle　beam-scanning　antenna　operating　in　the　ka-band　frequency　range.　Our　antenna　design　is　based　on　the　folded　transmitarray　concept　and　offers　a　low-profile,　high-gain　solution　for　wide-angle　beam-scanning　applications.　To　improve　the　antenna＇s　performance,　we　use　the　bifocal　technique　to　compensate　for　phase　variations,　reducing　gain　loss　within　the　scanning　range.　We　simulated　the　antenna＇s　performance　using　Ansys　HFSS,　which　showed　that　it　can　scan　within　a　range　of　±28°,　with　a　peak　gain　of　22.7　dBi　and　a　maximum　gain　loss　of　1.4　dB.　©　2023　IEEE.
