Abstract: An electronic device is provided. An electronic device includes a radio frequency integrated circuit (RFIC) chip, and an antenna array electrically connected to the RFIC chip, the antenna array including a first face and a second face facing each other in a first direction, and a third face and a fourth face connecting the first and second faces to each other and facing each other in a second direction intersecting the first direction, the antenna array including a plurality of substrates sequentially stacked in a third direction intersecting a plane defined by the first and second directions, first and second antenna modules on the plurality of substrates and sequentially arranged along the first direction, a first metal partition-wall including at least one metal via extending through the plurality of substrates in the third direction, and a second metal partition-wall surrounding the first to fourth faces.

Abstract: 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.
