1. A dual mode antenna, comprising:
a first conductive piece connected to a routing substrate; and
a second conductive piece connected to the routing substrate, the second conductive piece configured to electromagnetically couple with the first conductive piece through a dielectric spacer at a second frequency to operate as a loop antenna with the first conductive piece,
wherein the dielectric spacer is suspended over the routing substrate between a first member of the first conductive piece and a second member of the second conductive piece, wherein the first member is parallel to the second member along a first direction, and the first member does not overlap with the second member along the first direction.
