Abstract
Various embodiments of millimeter-wave systems on a printed circuit board, including a microstrip, a probe, and an RF integrated circuit, as well as methods for manufacturing said systems. Various embodiments have holes extending through lamina in the PCB, thereby improving radiation propagation. Various embodiments have conductive cages created by multiple through-holes extending through lamina in the PCB, thereby increasing radiation propagation. The manufacture of such systems is easier and less expensive than the manufacture of current systems.
Claims26
A system operative to inject and guide millimeter-waves through a printed circuit board, comprising:
- a printed circuit board comprising at least first and second laminas;
- a probe printed on the first lamina;
- a hole extending through the first and second laminas, such that said hole (i) substantially engulfs the probe and (ii) forms a wall inside the printed circuit board;
- and
- an electrically conductive plating, applied on parts of the wall that do not directly surround the probe;
- wherein the system is operative to radiate millimeter-waves from the probe, and guide said millimeter-waves through the hole.
A method for cost-effectively constructing a system operative to inject and guide millimeter-waves through a printed circuit board, comprising:
- printing (i) a probe and (ii) a microstrip comprising first and second ends, on a top lamina of a printed circuit board, such that said probe is connected to the second end of the microstrip;
- cutting a hole extending substantially perpendicularly through the top lamina and through all other laminas of the printed circuit board, such that said hole substantially engulfs the probe but does not engulf the first end of the microstrip;
- applying an electrically conductive plating on inner surfaces of the hole, thereby creating a laminate waveguide structure;
- and
- creating a clearance for the probe, by removing a part of the electrically conductive plating that directly surrounds the probe, thereby allowing the probe to radiate millimeter wave into the laminate waveguide structure.
A system operative to inject and guide millimeter-waves through a printed circuit board, comprising:
- a printed circuit board comprising at least first and second laminas;
- a plurality of plated through-holes going through the first and second laminas, such that said plated through-holes form a conductive cage inside the printed circuit board, said conductive cage having an opening;
- a microstrip printed on the first lamina, extending from a location outside the cage to a location inside the cage via the opening;
- and
- a probe printed on the first lamina, said probe located substantially inside the cage and electrically connected to the microstrip;
- wherein the microstrip is operative to feed the probe with an electrical signal, the probe is operative to form millimeter-waves corresponding to the electrical signal, and the cage is operative to transport said millimeter-waves through the printed circuit board.
