Abstract

A transmitter includes a 3-dimensional antenna array including a plurality of antenna elements, each antenna element having a radiation pattern, wherein the radiation patterns mutually overlap. The plurality of antenna elements is adapted for coherent wireless communication in a wireless communication system. The 3D-antenna array includes first and second and third antenna elements spanning a 2-dimensional antenna plane, and includes a fourth antenna element arranged outside the 2-dimensional antenna plane; or the 3D-antenna array includes a first antenna element configured to direct a transmitted signal into a first direction, and a second antenna element configured to direct a transmitted signal into a second direction and not into the first direction. The transmitter further includes a precoder connected through the 3D-antenna array, to form one or more transmit beams and/or receive beams with the 3D-antenna array.
