Abstract
The usage of electrically very small antennas in near field region (NFR) is fundamentally different from the usage in far field region (FFR). FFR and NFR are compared and summarized in Table. 1. The principal target in the design of the FFR applied electrically small antennas is to lower the Q factor whose limit has been given by LJ. Chu in 1948 [1]. On the contrary, the NFR applied antennas are desired to be non-radiative and lossless with as high Q value as possible. The Copernican-like revolution is necessary in the designer´s mind.
