Abstract

A novel transparent millimeter wavetransmitarray antenna (TA) using three layers of meshedmetal double circle rings elements is presented in this paper. Atransparent plastic material, polymethylmethacrylate (PMMA)is used as the substrate. In order to promote the transparency,a meshed double circle rings unit-cell is designed using several50 μm width metal grid lines. Good agreement between meshedand non-meshed unit-cells is reached at Ka-band. Atransparent TA with diameter of 9.9 wavelengths is designedand simulated by the commercial software Ansys HFSS at Kabandusing the proposed elements. By moving the feed alongthe focal plane of TA, beam scanning up to 30° with low sidelobe level, low cross polarization level and widebandperformance is reached.
