Design and experimental verification of a 3D magnetic EZ antenna at 300 MHz
FREE-DOWNLOADRW Ziolkowski, CC Lin, JA Nielsen… – Antennas and …, 2009 Abstract—Several variations of a 300-MHz version of the electri- cally small coax-fed three-dimensional (3D) magnetic EZ antenna were designed and tested. The final version of this low-profile antenna had an electrical size that was 0 437 at 300.96 MHz. Nearly complete matching to the 50
Novel fractal antenna arrays for satellite networks: Circular ring sierpinski carpet arrays optimized by genetic algorithms
FREE-DOWNLOADK Siakavara – Progress In Electromagnetics Research, 2010 – Abstract—A novel fractal antenna-array type is proposed. The design is based on the Sierpinski rectangular carpet concept. However, the generator is a circular ring area, filled with radiating elements, so the higher stages of the fractal development produce large arrays of circular
