Millimeter-Wave Microstrip Antenna Array Design and an Adaptive Algorithm for Future 5G Wireless Communication Systems

Figure 3

(a) Comparison of the simulated radiation patterns of a single antenna using HFSS and a 64-element array antenna with element spacing of = 5.5 mm and = 8 mm through (2) in E- and H-planes (- and - planes). (b) Comparison of the H-plane radiation pattern with and without the adaptive algorithm, demonstrating the nulls on the interference directions ( and ) of 13° and 0°, 30° and 0°, and 50° and 0°, respectively. (c) 3D radiation pattern of the array. (d) 2D contour of the radiation patterns.
