High-gain wideband and superdirective electronically-beam-switchable antenna for smart communication objects

Abstract : This paper proposes the design of a high-gain, wideband, directive, and compact circular array composed of 5 symmetrical radiating elements (1 fed and 4 parasitic elements). The possibility to implement an electronically beam-switching capability over the horizontal plane is studied. Thanks to the superdirectivity principle, the proposed closely spaced parasitic antenna array achieves a maximum gain of 10 dBi steered in four directions on the horizontal plane and a minimum gain of 9 dBi in the whole horizontal plane. The proposed antenna achieves a stable gain > 9dBi in the frequency band 758-803 MHz, which is interesting for sub-GHz 5G applications.
