Performance analysis of a flexible wearable antenna with low SAR for biomedical application
Abstract This article presents a conformal monopole antenna for wearable application in ISM band frequency of 2.45 GHz. The antenna has a return loss of 50.18 dB with good radiation performance. The gain of the antenna is 1.09 dBi which is improved to 3.28 dBi using a metasurface consisting of 3 × 3 array elements. The proposed metamaterial integrated antenna is fabricated on 1 mm thick flexible PDMS substrate. The metamaterial improves the gain while reducing the specific absorption rate (SAR) of the antenna. The geometry size of the metamaterial integrated antenna is 50 × 50 × 24 mm3. The loading effect of antenna by body is analyzed with a hand phantom model. Flexibility and conformability of antenna is analyzed by bending the antenna with various radii in x and y direction. Measured results of the fabricated prototype demonstrate the safety of the suggested wearable antenna for biomedical applications.
期刊介绍：
Frequenz is one of the leading scientific and technological journals covering all aspects of RF-, Microwave-, and THz-Engineering. It is a peer-reviewed, bi-monthly published journal.
Frequenz was first published in 1947 with a circulation of 7000 copies, focusing on telecommunications. Today, the major objective of Frequenz is to highlight current research activities and development efforts in RF-, Microwave-, and THz-Engineering throughout a wide frequency spectrum ranging from radio via microwave up to THz frequencies.
RF-, Microwave-, and THz-Engineering is a very active area of Research & Development as well as of Applications in a wide variety of fields. It has been the key to enabling technologies responsible for phenomenal growth of satellite broadcasting, wireless communications, satellite and terrestrial mobile communications and navigation, high-speed THz communication systems. It will open up new technologies in communications, radar, remote sensing and imaging, in identification and localization as well as in sensors, e.g. for wireless industrial process and environmental monitoring as well as for biomedical sensing.
