摘要： The antenna includes a main body, a first elastic film, a first medium, a curvature adjustment unit and at least one antenna unit. The first elastic film is adhered to the main body, and the first elastic film and the main body are encircled to form a first volume variable cavity. The first medium is filled in the first volume variable cavity, the first elastic film is elastically deformable according to a volume or pressure change of the first medium; the curvature adjustment unit is configured to adjust a curvature of the first elastic film through the volume or pressure change of the first medium; and the at least one antenna unit is adhered to an outer surface of the first elastic film and configured to receive or send a wireless signal. The beam direction of the antenna may be very flexibly changed in a large range.

摘要： The invention is directed to deployable reflectarray antenna structure. In one embodiment, the deployable reflectarray antenna structure includes a pair of flexible electrical elements, a feed antenna, and a deployment mechanism that employs a plurality of tapes to respectively transition the pair of flexible electrical elements from an undeployed state in which the elements are folded towards a deployed state in which the deployment mechanism and electrical elements cooperate to form a reflectarray and a subreflector of a reflectarray antenna structure. Further, the deployment mechanism also operates to position the reflectarray and subreflector relative to one another and to the feed antenna so as to realize a reflectarray antenna structure.

摘要： Controllable directional antenna apparatus and method preferably includes structure and/or steps whereby a Yagi antenna array has a first driven element, a first reflector, and plurality of first directors disposed on a common substrate. The first reflector is bent such that (i) an unbent length thereof is longer than a length of the first driven element, but (ii) a bent length thereof is shorter than the length of the first driven element. A second driven element is also disposed on the common substrate but is angled with respect to the first driven element. A second reflector and a plurality of second directors are also disposed on the common substrate. The second reflector is bent like the first reflector, to reduce the footprint of the array on the substrate. Preferably, the Yagi antenna elements are printed on a printed circuit board.

摘要： A ship having identifiable radar hot spots along its length is protected against radar homing missile attack by a floating decoy, which may be towed. The decoy has a plurality of radar return signal generators spaced along its length, with the amplitudes and spacing of the generators emulating the amplitudes and spacing of the hot spots. The homing missile is seduced away from the ship and toward the decoy.

摘要： There is provided an antenna reflector including at least first and second reflector segments, each having first and second sides. The first and second reflector segments being configured to be connected together wherein the first sides of the first and second reflector segments define a substantially continuous surface of an antenna reflector. A first latch member is attached to the second side of the first reflector segment and a second latch member is attached to the second side of the second reflector segment. Each latch member includes an abutting surface which contacts one another when the first and second reflector segments are connected together. At least one protrusion extends from the abutting surface of the first latch member. There is at least one recess in the abutting surface of the second latch member. The protrusion is received in the recess when the respective abutting surfaces contact one another.

摘要： Reflector systems (10) comprising a reflector (11) formed from rigid panels (14) mounted on a centrally-located hub (12) are provided. The panels (14) can be stowed in a relatively compact manner in which the panels (14) overlap. The panels (14) can translate with a combination of rotational and linear motion so that the panels (14) become disposed in a side by side relationship, thereby deploying the reflector (11) so that the reflector (11) can focus electromagnetic energy incident thereupon.
