  • Patent number: 7577464
    Abstract: A compact, non-phased-array, electronically reconfigurable antenna (ERA) system with at least two operational modes has a first operational objective that is polarization-sensitive null steering (PSNS) and a second operational objective that is direction-finding (DF). The system can rapidly switch between two operational states. In the first state, the system behaves like a polarization filter (PF) and operates as a controlled reception pattern antenna (CRPA), while in the second state the system behaves as an angle-of-arrival (AOA) sensor and operates as a fixed reception pattern antenna (FRPA). The system may include a spiral-mode antenna with both feed and load ports; a mode-forming network; an electronics package; and feedback control electronics. Radio frequency (RF) interference rejection and RF direction-finding may be performed as well as reduction and/or elimination of multiple jamming signals that are intentionally or unintentionally directed at a Global Positioning System (GPS).
