Antenna-in-package design for wireless ingestible capsule

An in-package antenna is proposed for a wireless ingestible capsule operated at ISM (2.4–2.48 GHz) band. The proposed antenna is designed for data transmission between the ingestible capsule and a smart phone using the Bluetooth technology. A modified planar inverted-F structure is implemented for the antenna design, in order to follow the shape of the spherical dome end. A one-layer cube muscle phantom model is used for the design, evaluation and optimization.
