Abstract
Antenna arrays can be fabricated as patches on conductive transparent material over an appropriate transparent dielectric substrate with the appropriate transparent ground-plane. To keep the fabrication cost low, such antenna arrays have a planar design without cross-over of the feeding lines or 3D interconnects. To steer the antenna horizontally, patches need to be fed with incremental phase shifts relative to their left or right neighbors; such feeds require an appropriate network and RF switches, typically located in an adjacent non-transparent area such as a PCB. Fabricating and disposing transparent phase delay component on the transparent material reduces the size of the PCB, thereby increasing visible transparent area.
