Abstract :
This paper presents investigation of multi-null-steering antenna array. A new method of nulling is based on controlling signal amplitude in the feeder network, which includes ring hybrid couplers, attenuators and power dividers. A basic concept verified by experiment, concerning single-null-steering antenna array and a simple way to extend this circuit to obtain more degrees of freedom in multi-null steering is shown and analysed
