Dual-Band Bi-Directional Pattern Reconfigurable Fractal Patch Antenna for Millimeter Wave Application

摘要

A novel dual-band bi-directional reconfigurable antenna based on Koch patch is presented in this paper. By controlling the switches in the slots etched on the Koch patch, different far field bi-directional patterns at the dual-band around 60 GHz/80 GHz could be achieved. And full azimuthal coverage at this dual-band is possible by electronically controlling the switches in the slots of the patch.
