Fractal J-pole antenna

2016 26th International Conference Radioelektronika (RADIOELEKTRONIKA), 2016
A super J-pole antenna with two fractal Koch curve shaped elements is proposed in this paper. In order to increase the bandwidth and to provide the proper phasing of the currents in the antenna elements a duplexer type phasing section is designed. The antenna performances (radiation patterns, VSWR and gain) are simulated and optimized for GSM-1800 ...

The fractal loop antenna: a comparison of fractal and non-fractal geometries

IEEE Antennas and Propagation Society International Symposium. 2001 Digest. Held in conjunction with: USNC/URSI National Radio Science Meeting (Cat. No.01CH37229), 2002
Fractal antennas have been shown to demonstrate repetitive multi-band or log-periodic behavior that has been attributed to the self-similar scale factor of the antenna's geometry. Additionally, fractal loop antennas have been shown to demonstrate improved impedance and SWR performance in a reduced physical area when compared to non-fractal Euclidean ...

Simulation of dendrite fractal antennas

2000 10th International Crimean Microwave Conference. "Microwave and Telecommunication Technology". Conference Proceedings (IEEE Cat. No.00EX415), 2000
Input characteristics of printed fractal antenna of dendrite type were simulated using the method of equivalent R-L-C circuits, whose topology is corresponds to the topology of the antenna. The results of simulation demonstrate good agreement with experimental data.

Printed circuit fractal antennas

2003 IEEE International Conference on Consumer Electronics, 2003. ICCE., 2003
Fractal antennas is a new member in the family of antennas. They have peculiar properties that make them interesting candidates for applications where wideband, multiband, input impedance, SWR are important parameters of the overall performance. The use of printed circuit fractal antennas is proposed, investigated, simulated and measured as part of ...

The theory of fractal antenna arrays

4th International Conference on Antenna Theory and Techniques (Cat. No.03EX699), 2004
Foundations of measure theory, the Hausdorff-Besicovitch measure, fractal nowhere differentiable Boltzano, Weierstrass, Cantor, Riemann, Darboux, Van-der-Waerden, Koch, Sierpinski, Besicovitch, and Weierstrass-Mandelbrot functions, and also some atomic functions possessing fractal properties are considered.
