It is common practice to use nonlinear, high-efficient power amplifiers to transmit non-constant envelope signals using concepts like LINC (linear amplification using nonlinear components). Traditional systems use a power combiner to reconstruct the non-constant envelope RF signal that is fed into the antenna. In this paper, we will investigate the integration of the power combiner with the radiator, resulting in a LINC power-combining antenna concept. Our novel concept uses two polarizations where the full reconstruction of the signal is done at the receiver side. System-level measurements at 2.45 GHz with 32-QAM signals show that our power-combining antenna concept out-performs traditional LINC implementations.
