Base Station Antenna For 5G Networks With Beam- Switching Capabilities At 3.5 GHz

Abstract

A circular conformal array antenna at 3.5 GHz having switching module for beamsteering is presented. A power amplifier to increase the power of the output signal is also presented. The individual radiating elements have been designed on microstrip patch. Power divider has been routed in octagonal shape to give omnidirectional pattern radiation output to microstrip patches. Beam-switching and beam-steering capability has been achieved by placing an electronic switching network between the radiating elements and the power divider. The antenna, power divider and switching network have been entirely manufactured by using printed circuit board. Due to this a cost-effective and compact antenna design has been achieved which is suitable for use as high gain base-station antenna for 5G communication network as well as a smart antenna providing both directional and omnidirectional applications. Key Words: Conformal array antenna, Beam-steering, Beam switching.
