A flexible meandered loop antenna is proposed, designed and realised for small cylindrical implantable devices. This antenna covers the Medical Device Radiocommunications Service (MedRadio) and the 433–434 MHz industrial, scientific and medical (ISM) bands, and is probably the smallest reported flexible implantable antenna that covers these bands. This antenna has shown a robust performance in the presence of implant internal components and has a realised gain of − 28.4 dBi inside a model of a human upper arm.
