Abstract :
In this paper, a dual-band microstrip patch antenna is designed and analyzed using metamaterial. The proposed antenna is tuned to work at two resonating frequencies in the frequency range from 1GHz to 5GHz. The antenna characteristics are studied before and after inclusion of metamaterial .we have also introduced Nicolson Ross-Weir method (NRW) method to achieve effectively the double- negative properties of the proposed metamaterial structure. The proposed rectangular microstrip patch antenna operates at the resonant frequency of 3.7GHz with a return loss of -37.24 dB.In addition to rectangular microstrip patch`s fundamental resonance; the additional resonance is obtained at 3.45GHz with a return loss of -36.4dB. To satisfy the demand of commonly used wireless communication systems, the metamaterial structure with microstrip patch antenna is designed with enhanced characteristics and exhibits dual bands. Hence the proposed antenna shows good results and can be effectively utilized for WLAN and RF-ID applications and mobile communication.
