A DOA receiver using RDRAs as receiving elements has been described. The receiver operates at 2.37 GHz. It has been demonstrated in the laboratory scale that the direction of arrival can be determined using the DOA receiver with two RDRAs. The receiver has benefited from the low level mutual coupling and low cross polarisation level of the RDRAs, which reduces the interference between channels and simplifies the design of circuits for phase measurements.
