摘要： Wireless communication is facilitated via communication assembly apparatuses. A system includes: a wireless gateway device located within a housing and having electrical connection elements for power and network connectivity; and an antenna coupled to the housing and electrically coupled to the wireless gateway device. The housing is adapted to be masked on a surface of a support structure exposed to a defined environment, and is configured to serve a first function and the support structure is configured to serve a second function. The first function is distinct from the second function. In various embodiments, the antenna can be a resonant slot antenna, a horn antenna, a dipole antenna, a patch antenna or a custom antenna element. The wireless gateway device can include circuitry that facilitates multiple-input and multiple-output communication of the antenna, and is configured to be powered via power over Ethernet in some embodiments. In various embodiments, the support structure can include, but is not limited to, a hand rail, a stage scaffold, a lamp post and/or a trash can.

摘要： An antenna (100) enables improved multi-band operation for a portable communication device, such as a portable two-way radio. The antenna structure is formed of a first radiator element (104) fed through a single radio frequency (RF) feed port (118) and terminated on the input of a transmission line (108). The transmission line (108) is routed along a ground plane reference mass (102) towards a second radiator element (106). Applying the antenna structure to a radio embodiment, the first radiator element (104) is placed at a bottom side of a portable radio device, the first radiator element being fed through the single RF feed port and terminated on the input of the transmission line. The transmission line is routed along the ground plane reference mass towards the second radiator element placed on a top side of the portable radio.

摘要： A phase-controlled antenna array comprises at least four phase-controlled elements which are connected via a feed network. Each antenna element comprises a waveguide emitter with a signal output coupling or input coupling and a phase actuator which is rotatably attached in the waveguide emitter and contains a mounting and two polarizers, wherein each of the two polarizers can convert a circularly polarized signal into a linearly polarized signal. The antenna elements additionally comprise a connection element and a drive unit which is attached to a support and which is connected to the phase actuator via the connection element such that the drive unit can rotate the phrase actuator about an axis of the waveguide emitter. The antenna array additionally comprises a computing unit which is connected to the drive unit(s) of the phase-controlled antenna elements via control lines and which adjusts the rotation of each phase actuator.
