Antenna device having circular array structure

Abstract

An antenna device having a circular array structure is disclosed. The disclosed device may include a multiple number of antennas positioned in a circular array and an upper board joined above the plurality of antennas, where each of the multiple antennas may include a reflector plate and at least one radiator joined to the reflector plate, and at least one FPCB joined to the reflector plates of a first antenna and a second antenna adjacent to each other from among the multiple antennas may further be included. The disclosed device can alleviate the performance degradation incurred by narrow reflector plates in an antenna device having a circular array structure and can provide radiation properties tantamount to essentially expanding the reflector plate of each antenna in an antenna device having a circular array structure.

Dependencies are inferred from the claim text.
