Abstract

The decoupling technique is for a group of antennae spacing for vehicle installations etc. the techniques is based on a first antenna having a null point in its lobe pattern and a second antennae so placed that the total field it receives from the first is zero. The first antenna has two element groups, arranged about those of the second, which are fed in phase and with equal amplitude signals.
