ABSTRACT:
A cordless communications system wherein transmission is made and received via magnetic lines of induction comprises a base station and at least one mobile station wherein the base station receives and transmits voice or data signals at different frequencies. The base station employs at least two magnetic loop antennas for transmission and reception, respectively, oriented so as to provide a toroidal magnetic field which allows 360 degree transmission and reception in the planes of the antennas. The components of the at least one mobile station are mounted in an article of clothing. The mobile station is arranged in the article of clothing in such a manner as to insure a substantially constant effective coupling area with the base station antenna.
