Abstract: An antenna mount for mounting radio antennas on a communications tower is described. The antenna mount includes a ring structure that encircles the tower and includes a channel disposed about its outer perimeter. The channel is configured to receive a plurality of antenna carriages upon which antennas are mounted on a first end. A second end of the antenna carriage is disposed in the channel and is slideably movable along the length of the channel about the perimeter of the ring structure. The antenna is thus aimable in any desired azimuthal direction by moving the antenna along the ring structure. Bands for communication of data, power, control signaling, and propulsion of the antenna carriages about the ring structure are disposed in the channel. The ring structure may include a junction that allows reorientation of antennas with respect to one another.

Abstract: Pedestrian transportable antenna systems can include an antenna mount and an antenna for satellite based or other communication mounted on a top face of the antenna mount. A bottom face of the antenna mount may be attached to a bendable rigid rod that is sufficiently rigid to provide support for the mounted antenna such that a user can walk around with the antenna deployed while the bendable rigid rod of the antenna system is mounted to the user's back (e.g., mounting into a back portion of a vest or flak jacket). The bendable rigid rod is sufficiently rigid to support the antenna without allowing the rod to “flop” over under the load of the antenna. At the same time, the rod is sufficiently bendable so as to permit the system to be drawn closer into a user's body when the antenna is not deployed (e.g., while stepping into a vehicle).

Abstract: An antenna system internal to the device especially intended for small-sized mobile stations, the system having separate operating bands. The system is implemented as decentralized in a way that the device (300) has a plurality of separate antennas (310-360). Each antenna is based on (a) radiating element(s) on the surface of a dielectric substrate. The substrate can be, for example, a piece of ceramics or a part of the outer casing of the device. The antennas are located at suitable places in the device. The operating band of an individual antenna covers the frequency range used by one radio system, the frequency ranges close to each other and is used by two different radio systems or only the transmitting or receiving band of the frequency range used by a radio system. If the device has a shared transmitter and a shared receiver for the radio systems using frequency ranges close to each other, there can anyway be a separate antenna for each system or the antenna can also be shared.
