Figure 6

Simulated results of modular addition when , , , . (a) The modular addition of the coding value in (a1), (a2), and (a3). The total modular addition is represented by and . The radiation pattern in (a1) is The radiation pattern in (a2) is . The radiation pattern in (a3) is . (b) 3-D radiation pattern. (c) Section view when , beam pointing is , 3 dB width is , and side lobe level is −8.92 dB. (d) Section view when , beam pointing is , 3 dB width is , and side lobe level is −9.04 dB.
