Abstract
Antenna systems are provided. An antenna system includes a beamforming array having a plurality of vertical columns of radiating elements that are each configured to transmit at least three antenna beams per polarization. Moreover, the antenna system includes a beamforming radio having a plurality of radio frequency ports per polarization that are coupled to and fewer than the vertical columns.
Claims23
An antenna system comprising:
- a beamforming radio having a plurality of first polarization signal sources and a plurality of first polarization radio signal ports, where each first polarization signal source is coupled to all of the first polarization radio signal ports;
- an antenna array having a plurality of columns of radiating elements;
- and
- a coupling circuit that includes a coupler and/or splitter that connects one of the first polarization radio signal ports to at least two of the columns of radiating elements.

An antenna system comprising:
- a beamforming radio having W first polarization signal sources and X first polarization radio signal ports, where W and X are positive integers, where each first polarization signal source is coupled to all X of the first polarization radio signal ports;
- an antenna including:
- an antenna array having Y columns of radiating elements, where Y is a positive integer that is greater than X;
- and
- Z first polarization antenna signal ports that are coupled to the antenna array, where Z is a positive integer;
- and
- a coupling circuit that includes a plurality of couplers and/or splitters, the coupling circuit coupling the Z first polarization antenna signal ports to the Y columns of radiating elements.
