This paper presents miniaturized industrial, scientific, and medical (ISM) band implantable antennas for wireless biomedical applications such as leadless pacemaker systems. The proposed single and dual-band antennas are proposed with a folded-shaped radiator and open-ended slot in the ground. The folded-shaped radiator is used to miniaturize the antenna, and the open-ended ground plane improves matching at the desired frequency. The proposed antennas operate at 2,460 MHz single band and 930 MHz and 2,450 MHz dual-band. The specific absorption rate (SAR) plots are plotted at 2,460 MHz for the single-band antenna and at 930 MHz and 2,450 MHz for the dual-band antenna. The suggested antennas' main advantages include their small size, reduced ground plane, low SAR, and acceptable gain values when compared to those of previous designs. Utilizing HFSS software, a homogeneous muscle box is created for the miniaturized antenna and its associated devices.
