Abstract:
A directional antenna comprising:an electrically conductive carrier plate; a substrate, mounted on the carrier plate, that includes a top surface at a height that is measured as a distance from the carrier plate; at least one printed wiring structure that includes: a first printed wiring on the top surface having a length and a width, the width of the first printed wiring being substantially shorter than the length, and a second printed wiring that couples the first printed wiring structure to the electrically conductive carrier plate; a lead-in printed wiring structure that is configured to provide a signal to the printed wiring structure via a capacitive coupling with the printed wiring structure; wherein the height of the first printed wiring on the top surface from the carrier plate is substantially larger than the width of the first printed wiring, to provide a directional radiation pattern relative to the carrier plate.
