Abstract: In one example, the present disclosure provides a dual-polarized antenna array that includes at least one unit cell. The at least one unit cell includes at least one radiating element of a first polarization state and at least two radiating elements of a second polarization state. The second polarization state is orthogonal to the first polarization state. The at least two radiating elements of the second polarization state are displaced on a first side and a second side of the at least one radiating element of the first polarization state.

Abstract: In one example, the present disclosure describes an antenna system with at least two linear antenna arrays, each having a plurality of antenna elements. Each array is designed to transmit and receive signals from different respective spectrum bands. The first antenna array and second antenna array are arranged to form one longer, combined linear array of antenna elements. In addition, at least one antenna element is shared between the first and second antenna arrays. In one example, the first antenna array is connected to a first RF distribution and phase-shifting network to distribute RF power and impart a phase profile across the first antenna array and the second antenna array is connected to a second RF distribution and phase-shifting network to distribute RF power and impart a phase profile across the second antenna array.

Abstract: In one example, an antenna system includes a radio base station for transmitting an RF signal via a transmission port, an RF splitting means for receiving the RF signal from the radio base station and for splitting the RF signal into two component signals, and at least two antennas separated by a distance greater than one wavelength and connected to the RF splitting means for transmitting the respective component signals such that an inferometric radiation gain pattern is created. The radio base station communicates with at least one mobile terminal via a dispersive multi-path radio channel where an angular spread of RF energy between the at least two antennas and the at least one mobile terminal causes nulls of the inferometric radiation pattern across a range of angles to be reduced.
