Hybrid fractal microstrip patch antenna for wireless applications

A dual band hybrid fractal antenna is presented in this paper. The proposed antenna resonates at 4GHz and 7GHz with frequency bandwidth of 1.05GHz and 570MHz respectively. This hybrid structure is the combination of Koch and Minkowski curve and can be used for satellite communication, WiFi, RADAR systems and radio telecommunication. As per the different number of iterations the performance results of Koch and Minkowski curve are compared with the proposed structure, which shows that the proposed design will operate well at both the frequencies (4GHz and 7GHz) of resonance as dual model for C band applications. IE3D software is used to design and simulate the proposed antenna. The experimental and simulated results are compared in terms of return loss, VSWR and radiation pattern.
