isolation minimize sij between antenna ports 43 46 and receiver inputs 51 54 the neutralization network 42 comprises eight couplers 55 eight coupler port terminators 57 and four transmission lines 56 which are used as phase shifters the design objective of the present invention is to reduce the coupling between the adjacent elements without increasing the coupling between the opposite elements this is accomplished by adjusting the phase shift in the network between the adjacent elements by adjusting the coupling line lengths and adjusting the amplitude coupling between the adjacent elements by adjusting the coupling line spacing the actual values of the coupling amplitude and phase shift should not equal the sij parameter amplitude and phase since exact cancelling of the adjacent coupling would have an effect of increasing the opposite coupling also there are no physical couplers or phase shifters between the opposite elements the only opposite element coupling present is via the electromagnetic field fig5 illustrates a block diagram of the antenna and neutralization network 42 far field signals arrive at antenna ports 43 46 u1 u4 as uncompensated outputs on antenna 41 as previously defined these signals are coupled between adjacent elements via eight directional couplers 55 and four phase shifters 56 which comprise the neutralization network the coupling amplitude adjustment is accomplished by adjusting.
