Disclosed is a human body wearable dual band antenna. The disclosed human body wearable antenna comprises: a substrate; a zeroth-order resonance antenna formed on the bottom of the substrate, for receiving a signal from a wireless device which is implanted in a human body; and a micro strip antenna formed on the top of the substrate, for transmitting the signal to a wireless device which is external to the human body. The dual band human body wearable antenna according to the present invention can relay communications between the wireless device which is implanted in the human body and the wireless device which is external to the human body. 1. A wearable antenna comprising:a substrate;a zeroth order resonance antenna formed on a lower part of the substrate, the zeroth order resonance antenna configured to receive a signal from a wireless device implanted in a body; anda microstrip antenna formed on an upper part of the substrate, the microstrip antenna configured to transmit the signal to a wireless device external to the body.2. The wearable antenna of claim 1 , wherein the zeroth order resonance antenna comprises a radiator and a ground plane claim 1 , the radiator formed on a lower part of the substrate claim 1 , the ground plane formed on a lower part of the substrate surrounding the radiator.3. The wearable antenna of claim 1 , further comprising a short-circuit column inserted in a via hole penetrating the upper part and the lower part of the substrate claim 1 , the short-circuit column electrically joined with a first feed line of the microstrip antenna formed on the upper part of the substrate and with a second feed line of the zeroth order resonance antenna formed on the lower part of the substrate.4. The wearable antenna of claim 3 , wherein the zeroth order resonance antenna comprises:a radiator formed on a lower part of the substrate;a ground plane formed on a lower part of the substrate; andat least one inductor joined with the radiator and the ground ...
