In this study, a micro-strip implant antenna that can be used in-tissue applications was proposed. Antenna size was designed as 30mm * 28mm * 1.59mm. In the design, a FR4 substrate material was used whose permittivity is 4.3, loss tangent is 0.025 and height is 1.52 mm. The analysis of the implant antenna was simulated in the CST Microwave Studio program. After obtaining the desired performance, a tissue model was created and an implant antenna was placed in the skin tissue. Return loss and SAR value of the designed antenna were measured in the 2.45 GHz ISM band. As a result, return losses were observed as -18 dB and -33 dB and SAR was 153 W / kg inside and outside the tissue respectively. Then, the antenna was manufactured with PCB and a phantom liquid was created that provides the electromagnetic properties of the skin tissue and the antenna was placed in this liquid. Finally, the simulation and experiment results of the designed antenna were evaluated and compared with literature studies. It has been observed that the measurement results in the skin tissue are well aligned with the simulation results.
