Abstract
The invention contemplates structure for improving the decoupling of helical transmitting and/or receiving antennas of at least one pair of antennas having oppositely directed circular polarization and which are perpendicular to an electrically conductive reflector wall. The device considerably increases the decoupling of such pairs of antennas by means of at least one electrically conductive partition wall which is disposed midway between the two antennas of a pair of antennas, particularly between a transmitting and a receiving antenna, the partition wall being also perpendicular to the reflector wall and electrically conductively connected thereto. Various embodiments are disclosed, ranging from the simple case of a single pair of antennas wherein the partition wall is flat, to a more complex case involving an array of four pairs of antennas wherein plural curved partition walls are employed.
