Multiple Receive Antennas - Site2

♦ The picture shows the first prototype of a uniform linear array (ULA)
made of 8 patch elements with an element spacing of 0.4 λ for a carrier frequency of 5.2 GHz

♦ The receiver's multiplexing scheme is illustrated below. The receiver is active only during the highlighted periods

, which equals to one period of the transmitted test signal

. The one period gap between successive antenna elements is required for switching and settling of the receiver processing chain.

♦ The switching is fast enough to capture the complete Doppler bandwidth of most real-world scenarios.
