Near-field measurements and far-field characterization of a horn antenna. (a) Visualized amplitude and phase distributions of the 24 GHz ± 40 MHz frequency-modulated continuous wave (FMCW) signal radiated from the horn antenna. (b) Simulation results for 24 GHz continuous wave (CW) signal. (c) Radiation pattern calculated from the near-field distribution. The black line represents the simulation results for the 24 GHz CW signal. (d) Measurement results of phase development in the Z-axis direction. The black line is the result of the simulation.
