Impact on focal parameters for near‐field‐focused aperture antennas

Near‐field‐focused (NFF) antennas have been studied to focus the electromagnetic power in the near‐field (NF) region of the antenna aperture over a long time. Some focal parameters have been adopted to evaluate the focused performance of NFF antennas. Research work on smaller NFF aperture antennas w...
