Planar ESPAR Array Design with Nonsymmetrical Pattern by Means of Finite-Element Method, Domain Decomposition, and Spherical Wave Expansion
Figure 4
Results for a monopole array, radius 10.5 cm, at 5 GHz. (a) 3D Polar representation of normalized power pattern calculated as a whole block. Values 10 dB below maximum are not represented. (b) 3D Polar representation of normalized power pattern calculated from the GSM of an isolated monopole. Values 10 dB below maximum are not represented. (c) Comparison of both cases on the azimuthal plane.
