Efficient HF Transmit Antennas Utilizing Platform Coupling Navy STTR FY2012.A Sol No.: Navy STTR FY2012.A Topic No.: N12A-T015 Topic Title: Efficient HF Transmit Antennas Utilizing Platform Coupling Proposal No.: N12A-015-0325 Firm: Virtual EM Inc. 3055 Plymouth Rd, Ste 200 Ann Arbor, Michigan 48105 Contact: Tayfun Ozdemir Phone: (734) 222-4558 Web Site: www.virtualem.com Abstract: Virtual EM is proposing a platform coupling technique for improving efficiency of electrically small antennas on ground, sea and air vehicles. The the proposed approach, a portion of the platform becomes the extension of the antenna and hence result in higher performance. Technique has been demonstrated already with the commercial automotive applications and a revised approach is proposed here. Benefits: Proposed antenna technology will be of immense value to military communication systems utilizing HF frequencies. Use of platform as part of the antnena is an innovative approach and will revolutionaize the way the HF anteannas are used on military platforms. Though the frequencu range is not applicable to commercial use, the propsoed innovation is applicable to antennas currently in use in commercial sphere (arcraft, automobiles, home applicances and celll phones).
