Reduction of Mutual Coupling between E and B Field Antennas in SQIF Arrays Navy STTR FY2010.A Sol No.: Navy STTR FY2010.A Topic No.: N10A-T015 Topic Title: Reduction of Mutual Coupling between E and B Field Antennas in SQIF Arrays Proposal No.: N10A-015-0737 Firm: Physical Sciences Inc. 20 New England Business Center Andover, Massachusetts 01810-1077 Contact: Francesca Scappuzzo Phone: (978) 689-0003 Web Site: http://www.psicorp.com Abstract: Physical Sciences Inc. (PSI), in partnership with the Electrical Engineering Department of the Worcester Polytechnic Institute (WPI), proposes to compute and reduce mutual coupling between E-field antennas (in Transmit mode) and SQUIDs magnetic loops (in Receive mode) for improved signal reception in SQIF arrays. For the computation of the mutual coupling in the near field PSI and WPI will use an exact quasi-analytical model based on Pocklington integral equation (Method of Moments - MoM). The selected electric antenna design will include a PSI patent pending antenna technology that has recently demonstrated excellent performance in antenna arrays for directed energy applications. The proposed research has direct applications to novel antenna technologies for Electronic Warfare (EW, SEWIP), Military Satellite Communications (MILSATCOM), and Signal Intelligence (SIGINT). Benefits: There are multiple potential commercial applications for the proposed technology, especially in the field of small directional antennas for mobile wireless systems. Directional antennas are used for Multi-Point systems for WiFi, for sharing a WLAN (Wireless Local Area Network) or a high-speed internet connection. They can also be used for WAP (Wireless Access Points) such as airports, RV parks, track stops, coffee shops, and schools. Small directional antennas can, also, have applications in indoor wireless systems. The proposed array sensor allows accurate localization of a source of emission. Commercial uses of direction finding technologies include emergency systems equipped with geo-location capability, geophysical measurements for sensing of underground resources (e.g. oil deposits), and medical diagnostics.
