Study on Realizing Isolation between Receiver and Transmitter at Array Antenna

The array antenna is widely applied in communication field.A group of antenna will have lots of input,while the self-excited phenomenon is objectively existed.The conventional way only works on a single role.It will consume lots of hardware resources to filter each role of array antenna with a single filter so that it is unavailable.This paper proposes a scheme to use parallel delay on 16 road input array antenna which will cancelling the echo signal.It will effectively reduce the hardware resources when this parallel structure is used.
