Description
Summary:This paper presents the design of an antenna array utilizing stacked multiloop structures to produce the electromagnetic radiations with dual circular polarizations and multiple directional beams. In particular, with a proper design of isolations, each combination of these polarizations and beams can be operated in a relatively independent fashion to increase the system capacity by using a single antenna set. The antenna structure was validated by numerical simulations and experimental measurements, which are presented to exhibit the characteristics of radiation. Key Points The design of an antenna array utilizing stacked multiloop structures Radiation with dual circular polarizations and three‐directional beams Provide the dual polarization and angular beam diversities
