Summary:
Metamaterials have an artificial structure, where unit cells are arranged at intervals shorter than the operation wavelength. Having their unique characteristics which are not found in nature, they have been receiving a lot of attention. For example, the size of a metamaterial antenna is smaller than that of a conventional one. Moreover, a composite right/left-handed transmission line (CRLH-TL) leaky wave antenna has wide beam directivity, so it can be applied to mobile communications. Recent studies have looked into the characteristics of CRLH-TL leaky wave antennas with linear polarization control by switching excitation mode (common mode and differential mode). Previously, we have proposed a new simple structure for the CRLH-TL circular polarization antenna, and confirmed the operation of circular polarization. In this paper, we propose a 2-dimensional CRLH-TL microstrip leaky wave antenna, which can operate with four different polarized waves, and show the result of the simulation.
