Abstract

A reconfigurable dual-band antenna with pattern diversity is proposed. By switching the dispersion curve of a composite right-/left-handed transmission-line-inspired structure, the antenna is able to realize both a broadside pattern and an omnidirectional pattern in both the 2.4835-2.5 GHz industrial scientific medical band and the 3.4-3.5 GHz WiMAX band. Despite its complex reconfigurability, only one feeding port is used. A small dual-frequency separation ratio is reached, which makes the antenna suitable for low-frequency range wireless communication systems. A prototype is fabricated and the measured results agree well with the simulated ones.
