Design of E and U Shaped Slot for ISM Band Application

Objectives: For implantable devices, a miniaturized antenna structure is proposed to operate in ISM band. At 2.5 GHz frequency the antenna is expected to operate. Methods/Statistical Analysis: A combination of E and U shaped slots on a rectangular patch design is proposed for biomedical applications especially operating in ISM band. The slots created here in order to changing the current path so that the radiation pattern acquired in excepted frequency. Findings: The E and U slots on a rectangular patch operates at 2.5 GHz and it provides good radiation pattern and gain. Applications/Improvements: Antennas dipped inside a human body are highly required for biotelemetry applications. Careful design of antenna is needed since the antennas are operated inside human body. The proposed structure gives good commitment towards the requirements.
