Virtual dipole signal amplification for in-body devices, such as implantable and ingestible devices, is provided. Aspects of the in-body deployable antennas of the invention include antennas configured to go from a first configuration to a second configuration following placement in a living body, e.g., via ingestion or implantation. Embodiments of the in-body devices are configured to emit a detectable signal upon contact with a target physiological site. Also provided are methods of making and using the devices of the invention.
