Abstract
This paper highlights the proposed design for a dual band Frequency Reconfigurable Monopole antenna fed through a 50Ω line feed over the Rogers substrate for GSM 900 and Wi- Max applications. The novelty of the proposed work lies in using two perpendicular strips loaded with Rectangular Complementary Split Ring Resonator in the Ground plane. The Monopole antenna is proposed to tune between two frequencies of 0.9GHz and 3.5GHz.The structure has been proposed on a Rogers's substrate of permittivity 2.2 with a thickness of 1.6mm.The radiating structure resulted in a Gain of 6.7dBi,8.429dBi,a Bandwidth of 80.5MHz, 144MHz for the lower and the upper frequency bands respectively. The structure resulted in a omnidirectional radiation pattern in the Wi-Max band.
