An antenna includes a telescopic antenna and an antenna jacket, where the telescopic antenna extends from a side opening and an exposed part of the telescopic antenna is configured to rotate outside the antenna jacket. The antenna and any one or more antennas of a GPS antenna, a Wi-Fi antenna, and a diversity antenna form a combination antenna. The GPS antenna and other antennas are disposed in an area adjacent to the antenna jacket.

There is provided a folding antenna device including a first case to which a first antenna is attached, a second case to which a second antenna is attached, and a hinge section configured to openably and closably support the first case and the second case.

A stacked patch antenna is expandable from a thinner stowed configuration in which the gaps between the conductor layers are reduced, to a thicker deployed configuration in which the gaps are expanded to their required dimensions. The expansion mechanism can include rotation of threaded rods, pneumatic expansion of telescoping rods, and/or injection of a gas, a chemical sublimate, and/or an expandable foam into the gaps. In embodiments, the stowed thickness of the antenna can be approximately equal to the sum of the thicknesses of the conductor panels. In some of these embodiments high dielectric layers are not included. In other of these embodiments high dielectric layers are formed by filling gaps with a high dielectric foam. Embodiments implement aperture coupling to the stacked patch antenna. An array of the stacked patch antennae can be folded about a satellite until deployment, and can be planar when unfolded and deployed.

In one embodiment, an apparatus is formed using a quarter wave (QW) patch element with a U-Slot, a ground plane, and a slotted shorting wall. A feed line runs through the ground plane and connects to the QW patch element. The slotted shorting wall connects the QW patch element to the ground plane. The QW patch element, slotted shorting wall, and ground plane are composed of a single contiguous folded material.

An antenna having an elongated housing open at one end and defining an interior chamber. A telescoping mast has a carrier attached at a first end and a flexible antenna attached at its other end. The carrier with the attached mast and antenna is movable between a storage position in which the carrier, mast, and antenna are contained within the interior chamber of the housing, and a deployed position in which the mast and attached antenna protrude outwardly from the housing. A spring is positioned between the carrier and the housing which urges the carrier towards its deployed position. A catch mechanism selectively holds the carrier in its stored position and, when released, releases the spring to move the antenna to its deployed position.

A case for an electronic device includes: a body configured to receive the electronic device; a connector configured to connect to a port of the electronic device; and an extendable phased array antenna structure integrated with the body and moveable relative to the body between a retracted position and an extended position. The extendable phased array antenna structure comprises an array of antenna elements that are configured to form a beam in a determined direction, the antenna elements being operatively connected to the connector by circuitry in the case.

An electronic device is to be worn by a user and includes an antenna and a storage compartment that stores the antenna. In a state of the electronic device being worn by the user, the storage compartment is positioned at a side of the user's head. The antenna is capable of selectively adopting a stored state and a deployed state, the antenna being stored in the storage compartment in the stored state, and a greater portion of the antenna being separated from the storage compartment in the deployed state than in the stored state.

A signal shielding and transmitting case with a length-adjustable antenna comprises a remote control part, a signal shielding case, and a PCB and an antenna driving part arranged in the signal shielding case, wherein a control line penetrates through the antenna driving part and is fixedly connected to a signal transmitting antenna, and the remote control part can control the length of the signal transmitting antenna stretching out of the signal shielding case based on the gear lever principle to allow users to adjust the intensity of signals transmitted by the signal transmitting antenna freely.

Portable skid assemblies are shown and disclosed. In some embodiments, the portable skid assemblies include a frame having two or more pockets sized to receive the fork of a forklift, telehandler, or pallet jack. The portable skid assemblies additionally include a support assembly having a base attached to the frame and at least one support member that moves vertically relative to the base between a retracted position suitable for at least one of storage or transport, and an extended position where the skid assembly is configured to communicate wireless signals.
