Abstract

A small circularly-polarized implantable antenna for long-term thyroid monitoring. The dual port loop structure proposed antenna covers a bandwidth of Wide band frequency 0.03 MHz - 6.02 GHz and it resonates at frequency of 2.45 GHz and 5.8 GHz which are mostly adopted for the WBAN and the medical telemetry applications. Antenna covers a super ultra-wide bandwidth due to the large operation band. An RO6010/droid 6010LM is selected as the substrate and the superstrate material within the compact design and its high dielectric constant and low loss are employed to minimize the size and improve the performance. The antenna footprint is 5 mm × 5 mm and its thickness are 0.57 mm in total. It demonstrates return losses of -22.45 dB at 2.45 GHz and -14 dB at 5.8 GHz. The antenna is -13dB (-19dB) at lower (upper) resonance frequency. SAR is studied by placing the antenna on the neck of human head model for human safety. The signal is well fastened yet dynamic in a dynamic environment, as a result of circular polarization. The simulation results exhibit satisfactory impedance matching and reasonable radiation efficiency, implying the proposed antenna is suitable to be used for the thyroid detection in biomedical applications.
