Embodiments of the present application relate generally to electronic hardware, computer software, wireless communications, network communications, wearable, hand-held, and portable computing devices for facilitating communication of information and presentation of media. An electrically conductive substrate (e.g., a metal or metal alloy) includes an antenna formed by a slot or opening formed in the substrate, and also includes at least one separate passive slot or opening (e.g., a passive slit) formed in the substrate. The antenna may be intentionally detuned from one or more target frequencies (e.g., 802.11, 2.4 GHz, 5 GHz) such that the antenna is not optimized (e.g., is not tuned) for the one or more target frequencies. One portion of the antenna may be electrically coupled with a ground potential. Another portion of the antenna may be electrically coupled with a RF receiver, transmitter, or transceiver. The antenna may be an active antenna, a passive antenna or both.
