Multi-element antenna beam forming configurations for millimeter wave systems

摘要

Multiple transmit antenna beam formers include/share a same set of power amplifiers and antenna elements to form multiple concurrent transmit antenna beams. Multiple receive antenna beam formers include/share a same set of antenna elements and low noise amplifiers to form multiple concurrent receive antenna beams. A transceiver includes the multiple transmit antenna beam formers and the multiple receive antenna beam formers, where the multiple transmit and receive beam formers include/share the same set of antenna elements. The transmit antenna beam formers and the receive antenna beam formers are configured to transmit, receive, and operate in the millimeter wave frequency band.

主权项

1. An apparatus, comprising a transmitter configured to:
modulate first and second radio frequency (RF) signals with respective first and second baseband signals; split each of the first and second modulated RF signals into multiple components; phase shift the components of the first modulated RF signal relative to one another; phase shift the components of the second modulated RF signal relative to one another; and output the phase shifted components of the first and second modulated RF signals to elements of an antenna to radiate the first modulated RF signal from the elements of the antenna in a first pattern and to radiate the second modulated RF signal from the elements of the antenna in a second pattern.
