Abstract

Methods and systems for a 60 GHz communication device comprising multi-location antennas for pseudo-beamforming are disclosed and may include configuring antennas in RF modules for beamforming transmitted signals. Each of the RF modules may receive IF signals via coaxial lines. The beamformed RF signals may be transmitted via the antennas to external devices. The RF signals may be generated from IF signals from baseband signals. The RF modules may be configured utilizing a processor in the wireless communication device. The RF signals may be transmitted to a display device. Control signals for the RF devices may be communicated utilizing the coaxial lines. The RF devices may be selected for the beamforming based on a direction to a receiving device. The beamforming may include adding a phase shift in upconverting the IF signals to the RF signals, which may include 60 GHz signals.
