Summary:
An alternative method for port decoupling and matching of arrays with small inter-element spacing is proposed. The approach is based on the inherent decoupling effect obtained by feeding the eigenmodes of the array. For this purpose, a modal feed network is introduced. The decoupled external ports of the feed network may individually be matched using conventional matching circuits. Such a system may be used in digital beam forming applications with good signal-to-noise performance.
