Abstract

See full text

A body-worn electronic device, including a loop antenna and a transmitter. The overall physical length of the loop antenna is less than 75% of the vacuum wavelength of a lower limit frequency of the operating frequency range of the transmitter, while the electrical length of the antenna is from 0.9 to 1.1 times the guided wavelength of the lower limit frequency of the operating frequency range of the transmitter. The loop antenna includes a plurality of conductors which are connected in series by inductors so as to increase the electrical length of the loop antenna.
