In this paper, an analytical method to characterize the frequency behaviour of Composite Right/Left Handed (CRLH) loaded printed dipole antenna is presented. One needs to determine the parameters of ungrounded reactive components realizing CRLH structures. Efficient resonant RLC circuit models based on Partial Elements Theory are presented to calculate inductance of meander line inductor and inter digital capacitor, while their capacitance is determined by Conformal Mapping Method. By using these circuit models and dispersion relation of balanced CRLH TL, negative resonance modes of antenna can be obtained. In addition, to validate the accuracy of the proposed analytical method, a prototype of the CRLH loaded printed dipole antenna is simulated, fabricated and measured.
