Abstract: An omnidirectional MIMO antenna system includes a multi-panel antenna, each panel including a plurality of antenna elements and a plurality of beam forming networks employing Butler matrices. Each Butler matrix has one less the number of input ports than output ports. The total number of the input ports of the Butler matrices is equal to the number of ports of the MIMO antenna, each of the input ports receiving the same signal. Each of the output ports of each of the Butler matrices is coupled to an antenna element within the plurality of the antenna elements, such that the multi-panel antenna exhibits a quasi-omnidirectional beam pattern.

Abstract: An antenna array with control circuitry placed at a front of the antenna array and between the antenna elements. By locating the azimuth beamforming network control circuitry on the front of the array and between antenna elements, the antenna elements and the other components can be coupled to the control circuitry without using cables. This leads to a reduction in the number of cable connections and to a reduction in size and weight of the resulting antenna array. The ABFN control circuitry is also used to control the beams formed from each row and not from each column as is usually done.

Abstract: An array antenna with each antenna element in the array being physically tilted away from a base plane of the array. End antenna elements are tilted at a higher angle than regular antenna elements. The radiation pattern, the end antenna elements can provide coverage directly above the antenna array (i.e. at 90 degrees to the horizontal) for different electrical tilts.

Abstract: An antenna producing a quasi-omni radiation pattern. The antenna includes at least three main panels, each having a plurality of radiating elements thereon, disposed in one or more columns of elements. The main panels are disposed in a substantially circular arrangement to generate the quasi-omni radiation pattern. At least one null filling panel is disposed between every two consecutive main panels of the at least three main panels, directed towards a null in the quasi-omni radiation pattern between the two consecutive main panels. The null filling panel has at least a single column of elements that radiate a null filling signal that is substantially the same signal as a signal from elements from the two adjacent main panels.

Abstract: Systems and devices relating to dipole antennas. The beamwidth of a crossed dipole antenna is widened by providing a parasitic monopole antenna adjacent to the crossed dipole antenna. In one configuration, each arm of the crossed dipole antenna has, adjacent to it, a parasitic monopole antenna. In another configuration, the crossed dipole antenna is surrounded by a number of other crossed dipole antennas acting as parasitic monopole antenna elements. The center or primary crossed dipole antenna can be for low band signals while the secondary crossed dipole antennas are for high band signals.

Abstract: A multi-beam antenna system, apparatus and method for dynamic carrier aggregation to multi-beam antenna mapping in radio access networks, including small-cell deployments, is disclosed. Apparatus comprises a compact base transceiver unit with integrated multi-beam antenna comprising antenna groups configurable for operation in a plurality of modes, with one or more selected antenna groups enabled, for different use-case scenarios. The base transceiver unit comprises a daisy-chained radio-frequency (RF) system wherein one baseband processor feeds multiple RF transceivers; each RF transceiver front end comprises a software configurable isolation module through which each RF front end is interlinked to previous and next RF front ends to enable dynamic routing of TX/RX data streams through the daisy chain, e.g. routing a transmission data stream from any RF transceiver to any one of the antenna groups or multiple antenna groups, routing a received data stream from one or multiple antenna groups to any RF transceiver, and for contiguous or non-contiguous carrier aggregation.
