Abstract

A millimeter-wave (MMW) communication system may include an antenna array structure operating within a MMW band, having both a first antenna coupling point and a second antenna coupling point, whereby the first and the second location of the antenna coupling points are within a coplanar surface on which the antenna array structure is formed. The system may further include a single MMW transmitter device having a power splitter that splits a data modulated MMW signal into a first MMW data modulated signal and a second MMW data modulated signal identical to the first MMW data modulated signal, such that the first data modulated MMW signal is coupled to the first antenna coupling point for radio propagation at a first direction, and the second data modulated MMW signal is coupled to the second antenna coupling point for radio propagation at a second direction.
