Conformal high frequency antenna
First Claim
1. An integrated driveshaft cover antenna, comprising:
- a driveshaft cover including a conductive layer, the driveshaft cover configured to be hingeably secured and electrically coupled to a helicopter tail boom section to cover a driveshaft access opening, wherein the driveshaft cover has a generally curved cross-section;
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, wherein the first surface of the dielectric layer is positioned over the curved outer surface of the driveshaft cover, and wherein the first surface is secured to the curved outer surface of the driveshaft cover; and
a slotted patch high frequency (HF) antenna layer having an inner slot, wherein the slotted patch HF antenna layer extends a majority of a length of the dielectric layer, and wherein the slotted patch HF antenna layer is secured to the second surface of the dielectric layer.

Abstract
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.
