Abstract
This paper presents the design of a metamaterial based dual band dual-polarized monopole antenna applicable for wireless applications. A monopole antenna is designed and loaded with a CRLH MTM inspired unit cell on either side of the substrate to operate as a dual band antenna with an improved impedance matching and circular polarization in one of the bands. The overall size of the antenna is 24 mm x 17 mm x 1.6 mm, operating at centre frequencies of 3.5 GHz and 5.5 GHz. Measurements were carried out and the impedance bandwidths obtained in the two bands are 940 MHz (26.8%) and 490 MHz (8.9%) with linear polarization in the first band and circular polarization with an axial ratio bandwidth of 150 MHz in the second band of operation. The obtained peak gains of the antenna in the two bands are 4 dBi and 5.1 dBi respectively, with a considerable agreement between the simulated and measured results.
