Title:
MODULAR PHASED ARRAY WITH IMPROVED BEAM-TO-BEAM ISOLATION
Document Type and Number:
WIPO Patent Application WO2004013930
Kind Code:
A3
Abstract:
A modular phased array antenna provides a reduction in the error signals that are introduced into beam signals by electromagnetic coupling that is inexpensive and does not cause an increase in weight in power consumption. A modular phased array antenna has irregular or random connections of beam signals to beam ports of each modular antenna assembly so as to provide improved beam-to-beam isolation. A modular phased array antenna comprises a plurality of modular antenna assemblies, each modular antenna assembly having a plurality of beam ports, each beam port of a modular antenna assembly connected to a different beam signal, wherein the beam signals are irregularly connected to the beam ports relative to the modular antenna assemblies. The beam signals may be randomly connected to the beam ports relative to the modular antenna assemblies.
