Abstract :
In this paper, the resonant frequency and sensitivity characteristics of Hilbert curve fractal antennas is presented. Several fractal-shaped Hilbert monopoles have been constructed, based on theoretical calculation, EM simulation and measurement. The formulation on resonant frequency of the Hilbert antennas is derived and verified. Experimental results show that compared with the receiving antenna for DRM (Digital Radio Mondiale) system provided by a professional company, our receiving antenna has a high enough receiving sensitivity but a reduced size.
