Generalized principle of pattern multiplication based on the phase antenna element

Abstract

The generalized principle of pattern multiplication is proposed based on the multi-mode phase antenna (MMPA). The multi-mode phase antenna (MMPA) has dual-port, and its beam direction can scan with the phase difference between dual-port. So the phase array based on MMPA element can be achieved by the array factor multiply the MMPA element factor, and the array beam can scan in wide angle with high gain if the array factor and MMPA element factor vary synchronously, this is the generalized principle of pattern multiplication (GPPM). Based on GPMM and MMPA element, we proposed a four-element E-plane scanning linear array. The main beams of the E-plane scanning linear array can scan from -65° to +65° in the frequency band at 1.5GHz.
