Abstract
A wireless communication system includes a plurality of antennas, and a plurality of RF chips, arranged in a row and coupled to the antennas, for providing a plurality radio-frequency (RF) output signals to the antennas according to an RF signal. The wireless communication system also includes a transmission line arranged to be a straight line in parallel to the row, and to connect to the RF chips, and a resistive load, coupled to a first end of the transmission line. A second end of the transmission line is arranged to receive the RF signal.
