Abstract
In a preferred embodiment, a wireless mobile system implementing Beam Steering Phased Array Antenna is disclosed having an array of [N×N] antennas mounting on the wireless mobile Terminal transmits unidirectional signals directly to the Base Station as opposed to transmitting multi-directional signals. The wireless mobile system implementing beam-steering phased array antenna, wherein the phases of the signals fed to the array antenna elements are varied by the phase shifters in small programmable step values calculated by the Digital Signal Processor (DSP) Phase Processor which causes the antennas radiation beam to be steered at angle θ. Thus, improvements in beam steering for transmitting unidirectional signals directly to the Base Station will greatly reduce the energy required by the wireless terminal for transmitting signals to the Base Station. And, the effective result would achieve our green-energy technology requirements.
