Abstract

. A multiband printed dipole antenna is presented for use in wireless
communication applications. The proposed fractal antenna design is based on
fractal geometry of the second level tent function transformation. Due to the
resulting geometrical structures of a fractal tent function curve depend on the
starting angles of the initial tent function, many dipole antennas have been
modeled and the corresponding radiation characteristics have been evaluated.
Theoretical performance of these antennas has been calculated using the method
of moments (MoM) electromagnetic simulator, IE3D. Simulation results of many
tent fractal dipole antennas which have been modeled show that all of these
antennas have multiband resonate behavior, but this resonate behavior is different
according to the starting angle for each antenna. The results have shown that these
antennas have acceptable performance for VSWR ≤ 2 (return loss ≤ -10 dB),
using a 50W feed line, at most of the resonating frequencies. This feature provides
antenna designer with more degree of freedom, and makes the proposed antenna
(or its monopole counterpart) suitable for use in the modern multi-functions
communication systems.
