Implantable antennas have recently been receiving substantial attention for medical diagnosis and treatment. In this article, a coplanar waveguide‐fed monopole antenna for industrial, scientific, and medical (ISM) band biomedical applications is proposed. The antenna has a simple structure that is placed on human tissues like muscle, fat, and skin. The designed antenna is made compatible for implantation by embedding it in a FR4 substrate. The proposed antenna is simulated using the method of moment's software IE3D by assuming the predetermined dielectric constant for the human muscle tissue, fat, and skin. The antenna operates in the frequency of ISM bands, 2.4 −2.48 GHz. Simulated and measured gains attain −7.7 and −8 dBi in the frequency of 2.45 GHz. The radiation pattern, return loss, current distribution, and gain of these antennas were examined and characterized. © 2014 Wiley Periodicals, Inc. Microwave Opt Technol Lett 56:1060–1065, 2014
