摘要

Antennas for Short Range Near Field UHF RFID Systems usually operate in proximity with the human body. Therefore, the robustness of such antennas with respect to body-coupling effects is a critical problem for the designer. For grounded antennas, a criterion for choosing a proper shape and extension of the antenna ground plane is specified, based on the relationship between the grounded antenna performance and the distribution of the electric and magnetic energy densities in the antenna nearfield region close to the ground plane border. Following these rules, it is possible to increase the antenna robustness with respect to the body-coupling effects, but with a minimal impact on the antenna size.
