A self-deployable antenna and/or antenna array that is made up of one or more antenna elements. Each of the antenna elements has a structural base that supports portions of the antenna and can be positioned between a stored configuration for compaction and a deployed configuration for transmitting. The antenna elements and structural base can be part of a base substrate that provides a base support for the antenna and/or antenna array to be compacted and deployed.

A deployable antenna structure is provided that, in one embodiment, implements an offset feed, cylindrical parabolic antenna. The antenna structure employs a semi-rigid panel that can transition from a stowed state characterized by the retention of substantial strain energy to a deployed state characterized by less strain energy than in the stowed state but more than if the panel were in a strain-free state and a portion of the panel having a shape that closely conforms to a cylindrical parabolic shape.

A portable satellite antenna (1) includes radiating elements (2), made of flexible shape memory material, attached to a main body (3) acting as a handle. In operation (W) of the antenna elements (2) are arranged in a fan-like radial pattern (X). When not operational (H) they are folded in a position (R) in which they adhere to the main body (3). For the definition and maintenance of the radiating elements (2) in the folded position (R), means of stabilization (4) are provided, such as a cap (40) or a band (41), or even a collar (42) or a sleeve (43), to be associated, in a fixed or removable way, to the main body (3) and radiating elements (2), which are capable of spontaneously returning to the fan-like radial configuration (X), corresponding to operation (W) of the antenna (1), as a result of the removal/opening of the means of stabilization (4).

A bendable antenna is provided. The bendable antenna is adapted to connect a cable. The bendable antenna includes an antenna body, a connection base, a first pivot base, a second pivot base, a first elastic element and a first restriction structure. The connection base is connected to the antenna body. The first pivot base is connected to the connection base, wherein the first pivot base includes a first recess. The second pivot base pivots on the first pivot base. The first elastic element is disposed in the first recess of the first pivot base, wherein the first elastic element is telescoped on the cable. The first restriction structure is connected to the connection base, wherein the first restriction structure pushes the first elastic element to restrict the first elastic element in the first recess.

A multi-band antenna has a feed point, a grounding location, a first portion for low band operation, a second portion for low band operation, and one or more portions for high band operation. The ground reference of the feed point for the multi-band antenna is connected to a separate object that may provide a base for the multi-band antenna. The feed point of the multi-band antenna may be spaced above the base and have a space between the feed point and a location for the ground point. The low band portion has multiple resonances that are often odd multiples of the lowest resonant response. The portions that resonant most dominantly in the high band often have multiple resonances that are even multiples of the lowest high band resonance. The multi-band antenna has resonances spaced closely enough to appear to be a wide band antenna above the fundamental high band resonance.

A dual-use spring attached to a small satellite that performs two common functions for small satellites including operating as a communications antenna for the small satellite, which eliminates the need for a separate antenna deployment step, and ejecting the small satellite from a modified deployment container mounted on a launch vehicle. The deployment container is modified by removing a conventional deployment spring and pusher plate, which increases available container space.
