Abstract
In this chapter, a single feed metasurface antenna with smooth dual-band frequency reconfiguration is proposed. The designed antenna has a simple and compact structure to be used in portable wireless communication devices. The antenna consists of two circular layers of substrate material placed one on top of the other. The lower layer is printed with a rectangular patch antenna in one side, and the other side is a ground plane. The upper substrate layer lay on top of patch antenna side is printed with a number of unit-cells on its upper side. To achieve frequency reconfiguration, the upper substrate layer is mechanically rotated at an angle θz in a clockwise direction along Z-axis. Based on rotation angle, the antenna scattering parameters (S11 and S21) of the unit cell are subjected to change which thereby affects relative permittivity of the upper layer resulting to a frequency reconfiguration.
