Abstract
A method of making a patch antenna includes the steps of: stamping a first metal plate to form a radiation metal layer having a first protruding portion; stamping a second metal plate to form a grounding metal layer having a second protruding portion; and attaching the radiation metal layer and the grounding metal layer to opposite surfaces of a dielectric layer to couple together the first and second protruding portions.
Claims2
A method of making a patch antenna, comprising the steps of:
- stamping a first metal plate to form a first plate body having a predetermined shape, and simultaneously, a first aperture in the first plate body and a first protruding portion that extends from a peripheral edge of the first aperture to thereby form a radiation metal layer;
- stamping a second metal plate to form a second plate body having a predetermined shape., and simultaneously, a second aperture in the second plate body and a second protruding portion that extends from a peripheral edge of the second aperture to thereby form a grounding metal layer;
- preparing a dielectric layer having a through hole;
- and
- attaching the radiation metal layer and the grounding metal layer to opposite surfaces of the dielectric layer to couple together the first protruding portion and the second protruding portion;
- wherein a first sub-feed-in hole is simultaneously formed when the first plate body is formed;
- a second sub-feed-in hole is simultaneously formed when the second plate body is formed;
- and a feed-in hole is formed when the dielectric layer is molded;
- the radiation metal layer and the grounding metal layer are attached to the dielectric layer that the first sub-feed-in hole and the second sub-feed-in hole are aligned with the feed-in hole before attachment.
