Abstract
In the field of biomedical research, continuous communication with a living body and data processing to take immediate actions on necessary points is the key concern. The advancing miniaturization of electronic devices combined with the latest evolution in on-body matched antenna is experiencing scrutiny in the biomedical telemetry. A miniaturized design of an on-body matched antenna along with its simulation-based parameter analysis is proposed in this paper. Industrial, Scientific, and Medical (ISM) band (2.4–2.5 GHz) allows a wider bandwidth with a considerably tiny size of the antenna and that is why the operating frequency of this designed antenna is tuned within this band. The proposed antenna is smaller in size and permits reasonable bend ability that improves its suitability for biomedical telemetry applications. The designed antenna's dimension is 12.150mm∗10.474mm∗1.488mm. The Microwave Studio of Computer Simulation Technology (CST) software is used to design the antenna with human phantom model and calculate various performance results, such as the return loss, radiation pattern, operating frequency, directivity, gain, total efficiency, power analysis and also sensitivity of the antenna in bending condition without changing the dielectric properties of human phantom model. Finally, the Specific Absorption Rate (SAR) is evaluated to check the biocompatibility of the antenna.
