Patent ID: 8482473

Claim:
A planar reconfigurable antenna, comprising: a substrate, having a first surface and a second surface; a metal layer, disposed on the first surface, an upper edge of the metal layer being in a convex arc shape, wherein the metal layer is electrically connected to a system ground and comprises a notch; a master antenna, disposed on the substrate and partially overlapping the metal layer on a vertical plane of projection, wherein the master antenna is symmetric with respect to a positive direction and the master antenna comprises: a first driving element, disposed on the first surface of the substrate and extended out from the notch of the metal layer; and a second driving element, disposed on the second surface of the substrate; an auxiliary antenna, disposed on the substrate and placed opposite to the master antenna along the positive direction; and a switch set, disposed on the substrate, the switch set changing a connection relation of a plurality of directors of the auxiliary antenna to switch a direction of main beams generated from the planar reconfigurable antenna.
