Smart Antenna with Capability of Beam Switching for 5G Applications

Abstract

A kind of smart antenna with capability of automatic beam switching is presented. The antenna comprises of three radiation elements, i.e. two directional elements for field coverage in far region and one omnidirectional element for field coverage in near region, so as to improve the overall received power along a straight path and realize high efficiency and energy-saving of antenna. To validate the idea, two cases of smart antennas with different structures of radiation elements are investigated for both cases of half space and confined space. In addition, measurements are carried out and the results are in agreement with that of simulation. This kind of smart antenna could be a promising candidate for 5G applications.
