An integrated driveshaft cover antenna includes a driveshaft cover including a conductive layer and having a generally curved cross-section. The driveshaft cover is hingeably secured and electrically coupled to a helicopter tail boom section to cover a driveshaft access opening. The integrated drive shaft cover includes a dielectric layer including a first surface shaped to conform to a curved outer surface of the driveshaft cover and a second surface opposite the first surface. The first surface of the dielectric layer is positioned over the curved outer surface of the driveshaft cover. The first surface is secured to the curved outer surface of the driveshaft cover. The integrated drive shaft cover includes a slotted patch high frequency (HF) antenna layer having an inner slot and extends a majority of a length of the dielectric layer. The slotted patch HF antenna layer is secured to the second surface of the dielectric layer.

Conformal high frequency antenna

Antennas, integrated driveshaft covers, and methods are disclosed. A particular antenna includes a dielectric layer. The dielectric layer has a first curved surface and a second curved surface opposite the first curved surface. A conductive body has a curved outer surface, where the first curved surface of the dielectric layer is positioned against the curved outer surface. A high frequency (HF) antenna layer is positioned over positioned over the second curved surface of the dielectric layer, where the HF antenna layer is curved to conform to the second curved surface of the dielectric layer. A pair of contacts may be configured to receive an electrical connection for the HF antenna layer. When an HF signal is applied to the pair of contacts, the conductive body interacts with the HF antenna layer to radiate energy.

Screen ink printed film carrier having an ink screen printed electrical altering image provided on thin adhesive film carrier that is flexible and capable of deformation out of the major plane of the carrier to conform to the exterior contour presented by flat or complicated three-dimensional objects, upon which the film carrier can be affixed.

Screen ink printed film carrier and electrically modulated device using same

An R-foam having a surface with an electrically resistive ink layer that is continuous and an electrically conductive ink layer that is in a predetermined pattern. The resulting surface is thereby electrically modified to have a predetermined resistive taper across it according to a predetermined resistivity curve. The method of manufacturing the R-foam involves printing the ink layers to the surface in a predetermined pattern that results in the predetermined resistivity curve. The ink layers may be applied using silk screening, stamping, and ink jet printing techniques.
