The frequency independence of fractal antennas

2013 IX Internatioal Conference on Antenna Theory and Techniques, 2013
Approach of fields and contours in an inhomogeneous medium is carried out by means of feeding into in consideration of fractal geometry devices. Fractal allocation electrical and magnet moments of alpha-poles is spotted on differintegral geometry devices.
