Abstract
An antenna is the interface between propagation of radio waves through electric currents and space moving in metal conductors. The reconfigurable antenna technique adaption is expected to have a significant impact in future wireless systems. Reconfigurable antenna is capable of modifying its frequency and radiation properties in a controlled and changeable manner. Tri-band antenna is an electronic device that can operate in three different frequency bands. The antenna is designed with the use of dielectric substrate of 1mm thickness with permittivity of 2.65. The design is simulated in ANSYS-HFSS based on the finite element method (FEM). In designed antenna, Antenna 1 operates in three frequency bands 1.781.84 GHz, 2.343.86 GHz and 5.755.87 GHz and Antenna 2 increases impedance matching of the third frequency band. Switching between the frequencies is achieved using metamaterials. The metamaterial antenna have advantages of minimizing the size and improves the compactness of antenna which is applicable to 4G wireless mobile communication system. Simulation result shows return loss for antenna 1 is -25 dB and return loss for antenna 2 is -27 dB. In future, by using metamaterials as substrate for Tri-band antenna we can achieve better antenna performance in terms of gain, efficiency and reduction of return loss.
