An antenna system for space applications provides a membrane antenna with one or more flexible membranes. An antenna enclosure stores the membrane antenna during stowage. One or more first deployable support structures extend along a first axis from the antenna enclosure during deployment, at least a first point of the membrane antenna being operably anchored to a point on the first deployable support structures. Deployment mechanisms are operably anchored at a junction with the first deployable support structures. The deployment mechanisms extend one or more second deployable support structures along a second axis from the first deployable support structures during deployment. At least a second point of the membrane antenna is operably anchored to a point on the second deployable support structures. Extension of the first deployable support structures and second deployable support structures unfurls the membrane antenna along both axes to overlap the junction.

Antenna tower construction/deconstruction biasing assemblies are provided. The biasing assemblies can be configured to extend between a standard and an antenna tower. The assemblies can include: an adjustable linear extension extending between a first end configured to couple with the standard and a second end configured to couple with the antenna tower; and a biasing mechanism configured to adjust the length of the linear extension and maintain the rigid engagement during transitioning of the tower from a down/erect position to an erect/down position. Methods for constructing/deconstructing an antenna tower are provided. The methods can include providing a biasing assembly.

A mount main body for a parapet-hanging-type antenna is provided with a vertical support column part (or VSC part) that vertically hangs down along an outer wall surface of parapet. The antenna is installed to VSC part so as not to protrude upward from the parapet. A horizontal support column part (or HSC part) that bends and horizontally extends in a direction orthogonal to the parapet is provided at an upper end of VSC part. The mount main body is provided with a cylinder holding HSC part such that HSC part is movable frontward/backward along a central axis thereof and is rotatable about the central axis. VSC part is made pullable to an inner wall side of the parapet by rotating HSC part about the central axis, and moving HSC part to the inner wall side of the parapet along the central axis.

Deployable tile aperture devices, systems, and methods are provided in accordance with various embodiments. Some embodiments include a device that may include multiple aperture tiles that may be coupled with each other such the multiple aperture tiles have a stacked stowed configuration and a flat deployed configuration. Some embodiments include one or more tension chords configured to deploy the multiple aperture tiles when tension is applied to the one or more tension chords. The flat deployed configuration may include at least one side edge portion of each aperture tile from the multiple aperture tiles making contact with another side edge portion of another aperture tile from the multiple aperture tiles. The flat deployed configuration may form one or more continuous face surfaces formed from the multiple aperture tiles. The one or more tension chords may pass through at least a portion of one or more of the multiple aperture tiles.

There are provided a multi-bay antenna apparatus and an operation method thereof. A multi-bay antenna apparatus may include a first section, a first array antenna mounted in the first section to receive a signal in a predetermined frequency band, a second section movably coupled with the first section, and a second array antenna mounted in the second section to receive a signal in a predetermined frequency band.

An apparatus for retaining a mobile computing device during data collection and field mapping procedures is disclosed. The apparatus comprises a base element configured to be gripped by a user, a shaft comprising a sliding traction mechanism and a first end, wherein the sliding traction mechanism extends from the first end, a clamping mechanism configured to be affixed to the shaft comprising a second end, wherein the first end and second end cooperate to define an interior space sized for retention of the mobile computing device, and a domed housing configured to house an antenna and a global navigation satellite system (GNSS) processor configured to be communicatively coupled to the mobile computing device.

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 radiofrequency (RF) localization system can include an RF sensing component, a signal-processing module and a visualization element. A plurality of antennas mounted on a belt, or on a helmet, or at least one extendable antenna attached within a backpack could be used for the RF sensing component. The signal-processing module can receive an RF Signal-of-Interest (SOI), and can further compute localization information for the RF SOI such as line of bearing, signal-to-noise ratio (SNR), and SSID information. The visualization element can be an augmented reality (AR) visor mounted on the helmet, or AR glasses. The signal-processing module can be mounted to the helmet, visor, or glasses, as applicable. The RF sensing component, signal module and said visualization element can be worn by the user, and can cooperate to provide hands free RF localization information in an AR format to an end user.
