—This paper presents a cost effective and simple anti-jamming method for global positioning system (GPS) antennas in the GPS L1 (1.563–1.587 GHz) band. The proposed structure is composed of a metallic conical structure with a microstrip patch antenna, which is selected as the basic element. To overcome intentional jamming signals coming from low elevation(More)
—In this paper, small dual layer spirals with several various ground structure are applied in the vicinity of the DDR3 high-speed circuit to achieve noise suppression characteristics up to 3.2 GHz region. For wider noise suppression bandwidth, the dual layer spirals with various ground structure, which provide high self resonance frequency (SRF) as well as(More)
