Abstract: A concealed antenna node for mounting on a street pole comprises an antenna with an associated radio module which are pre-wired together and housed within a radome of the concealed antenna node. The antenna comprises a plurality of antenna columns arranged about a central section within which the radio module is located. The antenna columns are arranged in a spaced-apart formation such that a gap is realised between adjacent antenna columns.

Abstract: The present invention is directed towards a Multiple-Input Multiple-Output (MIMO) omnidirectional antenna. The Multiple-Input Multiple-Output (MIMO) omnidirectional antenna comprising three or more column sets, where the three or more column sets are arranged in a centrosymmetric arrangement about a centre point of the antenna. Each column set comprises two or more antenna columns and each of the antenna columns mounts a plurality of radiators thereon. Each antenna column receives no more than two signals to be transmitted, and, each of the antenna columns is arranged to be axisymmetric about a radially-directed axis created between the centre point of the antenna and a transverse cross-sectional midpoint on the antenna column. Therefore, each radiation pattern established by each of the three or more column sets is centrosymmetric about the centre point of the antenna, and, is axisymmetric about the radially-directed axis.

Abstract: The present invention relates to a Multiple-Input Multiple-Output (MIMO) omnidirectional antenna comprising three or more column sets arranged in a centrosymmetricly. Each column set comprises two or more antenna columns, each having a plurality of radiators mounted thereon. Each antenna column receives no more than two signals to be transmitted, and is arranged axisymmetricly about a radially-directed axis created between the center point of the antenna and a transverse cross-sectional midpoint on the antenna column. Therefore, each radiation pattern established by each of the three or more column sets is centrosymmetric about the center point of the antenna and axisymmetric about the radially-directed axis. The MIMO omnidirectional antenna can fit within a radome of small diameter, while providing relatively uniform radiation plot coverage across a microcell where it is deployed. As no phase shifting is utilized, there is little ripple effect and all of the ports have a similar gain.

Abstract: An antenna assembly for a cellular telecommunications system has an antenna having an array (1) of radiating elements, for example patches, situated in front of a panel (2) having an electrically conductive face. An amplifier (6) for amplifying RFS signals received by the antenna is situated on the opposite side of the panel (2) from the radiating elements. The amplifier is situated at least partially within the signal shadow cast by the panel (2) so that the latter shields the radiating elements from the amplifier. The amplifier can thus be situated close to the antenna without adversely affecting the performance of the latter.

Abstract: A control means for controlling an antenna line device (6) in a radio telecommunications network in response to an input control signal has a plurality of possible modes of operation, in each of which the control means (26) is operable to receive, decode and implement the control signals in accordance with a respective protocol, and includes mode selection means (26) for selecting a mode of operation from a plurality of said modes. The control means can form part of the beam direction control apparatus (6) for an antenna, which itself can be connected to a base station of a mobile telecommunications system.
