Abstract

In this paper, a new method for increasing the total efficiency of a dual band compact antenna which usually has low values is presented. A newly-devised modified version of the SRR (Split Ring Resonator) is used to create another band with a higher total efficiency compared to those of the two bands and establish a configurable shift mechanism so as to merge it with the lower band of the original dual band. Not only does the total efficiency of the lower band of the dual band improved, the bandwidth also gets wider by this method. The size of the antenna we proposed is just λ0/8 × λ0/8 for the lower operation frequency even with low permittivity material (εr = 2.2) as substrates. The simulation results of s-parameters and total efficiency are provided.
