Abstract
A method and apparatus for transmitting a wireless signal using a beamforming apparatus having a plurality of antennas is disclosed. The technique comprises: generating a first RF signal; and transmitting, using the plurality of antennas, a corresponding plurality of output RF signals to form the transmitted wireless signal; wherein transmitting the plurality of output RF signals comprises, for each antenna: splitting the first RF signal into a pair of second RF signals; shifting a respective phase of each of the pair of second RF signals; adding the phase shifted pair of second RF signals to form a third RF signal; and transmitting, using the antenna, the third RF signal as the corresponding output RF signal for the antenna.
