Reduction of the In-Band RCS of Microstrip Patch Antenna by Using Offset Feeding Technique

Figure 10

Simulated and measured radiation patterns of the antennas from Figure 7 in the xoz-plane (H-plane): (a) copolar and (b) cross-polar components of the patch antennas and (c) copolar and (d) cross-polar components of the patch arrays. Note that  GHz for the symmetry offset fed patch antenna,  GHz for the edge center fed patch array, and  GHz for the symmetry offset fed patch array.
