Abstract：

In　this　paper,　we　have　presented　a　solution　to　generate　a　2D　focal　spot　array　that　does　not　need　to　be　optimized　and　has　the　characteristics　of　a　variable　quantity,　adjustable　gap,　and　location.　With　the　aid　of　a　planar　antenna　array　placed　at　the　focal　point　of　two　high　numerical　aperture　(NA)　objective　lenses　to　concentrate　the　field　radiation,　the　focal　spot　array　is　easily　achieved.　The　results　show　that　there　is　a　one-to-one　correspondence　with　the　array　elements　and　the　spots,　which　is　mainly　reflected　in　the　following　aspects.　The　location　of　the　spot　is　only　determined　by　the　corresponding　element,　the　number　of　spots　and　elements　are　equal,　every　spot　in　the　2D　focal　array　has　the　same　strength　distribution.　©　2022　IEEE.
