Abstract

In this presentation, we present a novel design of a compact, miniaturized dual-band antenna for implantable applications in the industrial, scientific, and medical (ISM) bands, operating at 2.45 GHz and 5.8 GHz. The proposed antenna has a compact form factor of 47.95 × 32.98 × 1.27 mm3. It achieves gain values of 0.32 dBi at 2.45 GHz and −6.5 dBi at 5.8 GHz, which are considered relatively high for implantable applications. The antenna is designed for a three-layer tissue environment, and a prototype has been fabricated and tested in real tissue to validate the simulation results. A comparison between simulated and measured performance is discussed in terms of reflection coefficient, transmission coefficient, path loss, and gain.

    Dr. Noor Badariah Asan is a Senior Lecturer in the Faculty of Electronics and Computer Technology and Engineering (FTKEK) at Universiti Teknikal Malaysia Melaka (UTeM). Her area of specialization is wireless communication systems with a special interest in biomedical applications. Dr. Asan graduated from UTeM with a Bachelor of Engineering in Electronic Engineering (Telecommunication Electronics) in 2008 and a Master of Engineering in Communication and Computer from the National University of Malaysia (UKM) in 2012. She obtained her Ph.D. from Uppsala University in Sweden, and her research focused on fat-intrabody communication (Fat-IBC), which involved the use of adipose tissue as a medium for intra-body wireless communication. Dr. Asan's research interests are Fat-Intrabody Communication (Fat-IBC), Bioelectromagnetics, Biomedical Implants, Antennas and Propagation, and Wireless Sensor Networks. She has written more than 36 publications and has been cited over 400 times. Her work has greatly helped in understanding the intra-body communication channels especially the role of fat tissue in transmitting microwave signals. Notably, her research showed that fat tissue can be a good medium for intra-body communication with less path losses than muscle tissue at frequencies such as 2.45 GHz and 5.8 GHz. Dr. Asan has worked with international researchers and participated in different conferences and workshops on microwave biomedical engineering. Her interdisciplinary approach connects the gap between electronic engineering and biomedical applications, which will create innovative solutions for healthcare monitoring and diagnostics.
