A guest engagement system and associated methods provide seamless engagement with guests of facilities through the use of wireless sensing technologies. The system makes use of individual guest devices which are carried by guests and used to automatically identify and authenticate the guests throughout the facility. Services can thereby be seamlessly provided to the guests throughout the facility. The services include automatic unlocking of doors, including hotel or state room doors, based on the guests' immediate proximity to their assigned room's door. The services also include automated payment services provided at checkout or vending terminals, and automated log-on to interactive displays and portals, among others, based on secure wireless authentication of the guest devices. Antenna devices and methods for making and using the same are disclosed. An exemplary antenna device can include first and second wireless communication antennas configured to operate using first and second communication standards, respectively.

Disk antenna includes a plurality of conductive plates forming a stack aligned along a principal axis. The plates include a ground plane plate, a plurality of electrically active plates, and a drive plate disposed between the ground plane plate and the plurality of electrically active plates. A mast is configured to transition from a first condition in which the mast is compactly stowed, to a second condition in which the mast is deployed. Suspension members are configured to couple a radiating end of the mast to the plurality of electrically active plates. The plates are compactly stacked when the mast is in the first condition, and urged to distributed locations along the length of the mast in the second condition.

The present invention relates to a foldable panel antenna which comprising a main body including a first vibrator, a first housing coating the first vibrator, and a feeder terminal; at least one side plate including a second vibrator and a second housing coating the second vibrator; and a rotating mechanism which is designed to connect the main body and the side plate and rotate the side plate around the main body, and the first vibrator is in electric connection with the second vibrator at the rotating mechanism. The foldable panel antenna can achieve the effects of compatibly receiving VHF/UHF signals, being easy to store, carry and transport, and effectively controlling the cost.

The present disclosure relates to the field of television receiving antennas, and discloses an outdoor antenna, comprising a main body and a pair of reflective nets, wherein the reflective net comprises an assembly body, the main body comprises a fixing base, the assembly body and the fixing base are plugged into each other, and the assembly body and the fixing base are connected by a snap-connection, which allows the assembly body and the fixing base to be tightly combined with each other after being plugged in. The reflective nets can be detached from the main body, so that the entire outdoor antenna can be disassembled, which avoids packaging of the entire outdoor antenna and reduces the packaging volume. Furthermore, through the snap-connection, the assembly body and the fixing seat will not be loosened after being plugged in, and can be tightly combined with each other.

An antenna is made from strips of a shape-memory alloy or other resilient material acting as a spring with attached branches that constitute individual monopole antennas. In the folded state, the antenna looks like a strip roll and can be placed on a satellite. When in orbit, the antenna unfolds after the roll retention mechanism is released and orderly unfolds unrolling from a support frame or otherwise extends. The proposed design of monopole branches utilizes conductors of minimum length and achieves maximum directivity. Each monopole branch is connected to the signal receiver/transmitter by signal conduit elements. A system may include at least two such unfolding antennas thus achieving even greater operational effectiveness in regard to signal steerability, interference suppression and reduced moment of the satellite inertia. To prevent problems, additional measures are used that prevent unwinding of inner layers of the roll before the outer layer is extended.
