Microwave and millimeter-wave antennas focused in their radiative near-field (NF) region, which are usually named as near-field focused (NFF) antennas, are becoming increasingly popular. Indeed, when compared to conventional far-field focused antennas, they can guarantee performance improvement at a relatively limited implementation cost, in short-range communication systems, wireless power transfer arrangements, remote nondestructive sensing setups, and radiofrequency identification apparatus, among many others. In this chapter, application fields and metrics for NFF antennas will be briefly summarized. Most of the chapter is then devoted to the description, classification, and critical review of the many synthesis techniques that go beyond the simple, yet effective and with a clear physical insight, conjugate-phase approach.

“…The shaping of the (scalar) near-field by resorting to convex optimization has also been applied in [16] when the antenna radiates in freespace, and then extended in [17] to account for the presence of lossy stratified media. Among the synthesis techniques for aperture antennas, in [18] a NFF reflector antenna has been designed by optimizing the on-axis field through an iterative approach that exploits the Fast Fourier Transform (FFT) to relate the aperture field to the on-axis field. The method was validated by designing a 1.2m diameter reflector at 95GHz, with quasi-constant beam radius from 25m up to 100m from the antenna aperture in the near-field region.…”
