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.
