2 Beamforming-I (10) Consider two antennas A and B separated by a distance of , and transmitting in-phase signals of wavelength . A receiver R is placed on a line passing through the mid-point of the two antennas and making an angle relative to them as shown in Figure 1 . Determine the phase difference between signals of A and B that arrive at R. Plot the phase difference as a function l, when l varies from 0 to 100 (provide three plots for three different values of -0, 90, and 45).
