Patch antenna using non-conductive frame

Номер: US0006421011B1

A non-conductive frame supports the resonators in a patch antenna assembly. The frame supports the resonators without making holes in the resonators and thereby avoids the problem of creating unwanted electric field polarizations. Additionally, the frame grasps the resonators in areas of low current density and thereby avoids creating additional disturbances in the radiation pattern. The frames may also include posts that are used to attach the frames to the feedboard without using additional components such as screws.

Patch antenna construction

Номер: US0006232923B1

The conductive layers corresponding to a patch antenna are formed on a single substrate, as by printing a conductive ink. The substrate is in the form of an elongated, non-conductive, flexible sheet with the consecutive antenna layers printed thereon side-by-side. The layers of the antenna can then be brought into superposed alignment by appropriate folding of the sheet. The non-conductive rectangles can be maintained in spaced alignment to the cut-outs by placing a porous non-conductive block of spacing material therebetween. In a preferred embodiment the assembled structure has the various layers bonded together.

Connector for differential-mode transmission line providing virtual ground

Номер: US0006677832B1

An electrical connecting element is disclosed comprised of a dielectric substrate having two conductor paths disposed on opposite sides and being substantially aligned with one another. The electrical connecting element employs differential-mode signaling such that the first conductor path carries a signal of opposite polarity to the second conductor path. A virtual ground exists between the differential + and - lines that permits an otherwise "groundless" differential transmission line. The substantial alignment of the first and second conductor paths improves the space constraints, relative to conventional electrical connecting elements. The characteristic impedance of the disclosed differential transmission line depends on the width of the trace lines the thickness of the dielectric substrate.
