A structure containing an antenna with an orientation which can be changed when one part of a two-part structure is turned relative to the other on a rotating shaft includes first and second structures as the two parts. The second structure is rotatably connected to the first structure through the rotating shaft, and the second structure comprises an antenna plate. When the second structure is rotated relative to the first structure, the rotated antenna plate allows a wider range of wavelength frequencies within the rotation range of the second structure.

A tilt bracket comprising a first bracket part and a second bracket part is pivotable between a fully open position, a fully folded position, and intermediate positions. The tilt bracket further comprises a blocking mechanism which allows the first bracket part and the second bracket part to always pivot towards the fully folded position, and which either prevents or allows the first bracket part and the second bracket part to pivot towards the fully open position.

An antenna mount for supporting an antenna on a support member in a manner which reduces the likelihood of the antenna, antenna mount and support member being damaged by an object making contact with the antenna. The antenna mount has a mounting plate connected to the antenna, a pivot mechanism connecting the mounting plate to the support member and a biasing mechanism interconnecting the pivot mechanism and an anchor associated with the support member. The pivot mechanism allows the antenna to move to a pivoted position in response to contact with an object. The biasing mechanism is configured to hold the antenna in a desired operating position during use and to move the antenna from its pivoted position back to the desired operating position after contact with an object. The antenna mount can be utilized with an upwardly extending tubular support member of a vehicle.

An electronic device includes a casing, a first antenna assembly, a second antenna assembly and a third antenna assembly. At least one of the first antenna assembly, the second antenna assembly and the third antenna assembly is rotatably disposed on the casing, and the rest are fixed on the casing.

An access point has a housing with at least one connector for at least one external antenna and at least one connector for at least one internal antenna. An RF controller detects whether the at least one external antenna is connected to the at least one connector for the at least one external antenna when an open circuit is closed. Responsive to detecting that the at least one external antenna is connected, a first mode in which the at least one internal antenna supports RF capabilities switches to a second mode wherein the at least one external antenna supports RF capabilities.

Embodiments of negative pressure wound therapy systems and methods are disclosed. In one embodiment, an apparatus includes a housing, a negative pressure source, a canister, an antenna, and one or more controllers. The negative pressure source can provide negative pressure via a fluid flow path to a wound dressing. The canister can be positioned in the fluid flow path and collect fluid removed from the wound dressing. The antenna can be supported by the housing and wirelessly communicate with an electronic device. The antenna can be oriented in the housing to face downward toward the ground when the negative pressure source is providing negative pressure. The one or more controllers can activate and deactivate the negative pressure source and transmit first data to the electronic device using the antenna or receive second data from the electronic device using the antenna.

An antenna positioner provided on a deployable vehicle. The antenna positioner includes a base and a frame having a plurality of plates oriented at an angle relative to one another. Each plate may include a low band antenna and a high band antenna. The base is located inside a chamber of the deployable vehicle. The frame is movable relative to the base between a collapsed position, where the entire frame is positioned within the chamber, and an extended position wherein at least a portion of the frame extends outwardly through an opening in the deployable vehicle's exterior wall. The frame is pivotally engaged with the base and a gearing mechanism pivots the frame between the collapsed position and the extended position to arrange the antennas at a desired orientation relative to the deployable vehicle's exterior wall so as to maximize the antenna's near-vertical Field of View (FoV).

A fin-type planar antenna and a deployable dipole antenna are combined into a probabilistic system as a co-located orthogonal diversity fin antenna to reduce or eliminate cross polarization fades and cancellation dropouts common to wireless audio systems used in theaters, churches and convention centers over coaxial wired connections. Additionally, an optical line may connect the diversity fin antenna to a further circuit. The antenna system features broad bandwidth, resistance to deep nulls or fades caused by cross polarization, resistance to destructive interference, and an air space dielectric covering provides resistance to detuning in the presence of rain, or touching objects.

An antenna apparatus comprising at least one antenna array configured to produce a beam to facilitate wireless communication with at least one other antenna apparatus is described, in which the beam can be electronically steered in an associated beamforming plane by beamforming circuitry. The at least one antenna array has an associated antenna array plane, and an antenna array rotation mechanism is configured to rotate each antenna array in its associated antenna array plane to cause its beamforming plane to rotate. Methods for operating such an antenna apparatus, and for deploying an antenna apparatus in a wireless communication network, are also described.

A wireless antenna module includes a housing, at least a wireless antenna a main controller and an externally connection connector provided to the housing. The main controller has at least a processor which performs handling of information with other devices connected via the external connection connector.
