The paper discusses the problem of side lobe suppression in the radiation
pattern of printed antenna arrays with different 3D reflector surfaces. The
antenna array of eight symmetrical pentagonal dipoles with corner reflectors
of various angles is examined. All investigated antenna arrays are fed by
the same feeding network of impedance transformers enabling necessary
amplitude distribution. Considering the different reflector surfaces, the
influence of parasitic radiation from feeding network on side lobe
suppression is studied to prevent the reception of unwanted noise and to
increase a gain.
