Abstract:

A novel fractal iteration technique has been applied to a low-profile miniaturized monopole antenna. The resonant frequency of the antenna is 915MHz and the bandwidth is about 20MHz with vertical polarization. The fractal shape is applied to the open-circuited segment of the substrate to reduce the dimension of the substrate. At the same resonant frequency, the substrate dimension of the fractal antenna is 15% smaller than that of the reference antenna. An antenna prototype is fabricated based on the simulation. The simulated and tested results prove that the design is feasible.

Key words: fractal antenna, miniaturized, low-profile, vertically polarized
