Summary: | Emerging applications such as next generation wireless communications at mm-waves require active array antenna systems for meeting the high performance demands. This calls for new power-efficient and linear phased-array concepts. The combination of in-space outphasing of constant-envelope phase-modulated signals and a beamforming array is a promising architecture. In this paper, the influence of the outphasing configuration on the array factor and Error Vector Magnitude (EVM) is investigated. A prototype at 2.4 GHz was realized and characterized which shows good agreement with the theory. The outspacing array achieves an Error Vector Magnitude (EVM) of 5% without calibration. |
