Classification: CPC H | IPC H

Claim 0:
1. A resonant wearable antenna system, comprising:
a ground plane comprising a first cloth substrate and an array of metamaterial (MTM) unit cells positioned thereon, wherein at least one MTM unit cell includes four four-leaf-clover units arranged in a four-leaf-clover pattern and connected to a center unit, wherein each four-leaf-clover unit includes four leaf units arranged in a four-leaf-clover pattern and connected to a subcenter unit; and
an antenna structure positioned over the ground plane, the antenna structure comprising a second cloth substrate and a conductive pattern positioned over the second cloth substrate,
wherein the antenna structure is configured to have a first resonant frequency below 1 GHz and a second resonant frequency higher than the first resonant frequency,
wherein the array of MTM unit cells is configured to reflect incident waves, from the antenna structure at the first resonant frequency and the second resonant frequency, in-phase.
