Abstract

PURPOSE:To ensure a stabilized communication by combining the communication equipment with a 90 deg. phase difference to both of a pair of the loop antennas whose inductive electromagnetic fields are right-angled to each other and the providing the transmitter-receiver antenna within the vertical surface in the passway of a mobile object.
