| Abstract | ||
| mmunication 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 | ||
