“…The S11 parameter which is known as reflection coefficient or return loss is the measurement of the power from an antenna which is radiated or reflected [22]. At resonant frequency, the return loss is noticed while implanting the pronouned antenna inside the designed phantom model and free space.…”

<span>This research work assumes the role of designing a Micro-strip patch antenna that exists with in the band range of 402 MHz to 405 MHz, which was considered as medical implantable communication systems (MICS) band and can be possibly implanted at human body phantom model because of its flexiblility and lower radiation characteristics. CST Microwave studio was used for designing the patch antenna and the human body phantom model with the existence of homogeneous layers (fat, skin and muscle) and the final version was fabricated. Being highly flexible, FR4 was chosen as a substrate to maintain 0.5 mm thickness throughout. For the ground and patch, copper material was selected having thickness of 0.018 mm. For the ease of fabrication and biocompatibility, silicon was selected with the thickness of being 8 mm. Maximum specific absorption rate of the proposed antenna was obtained 0.588 W/Kg for 10g tissue. Various Parameters such as VSWR, S11, Radiation efficiency, Total efficiency were found 1.1889, -21.28 dB, <br /> -45.71 dB, -45.74 dB respectively inside body phantom that ensure the antenna design was efficiently and effectively suitable for biotelemetry system which is body implantable. After fabrication the value of S11 is found -12.43 dB in open space with 453 MHz frequency.</span>

“…However, the tuning of the antenna could not be properly achieved resulting in a poor return loss in the ISM band. Later, an enhancement of the novel slot‐dipole design from [9] is seen in [10, 11] permitting a reduction in dimension by 50%. The new design enabled to properly tune the antenna – meaning that the antenna had all the same characteristics as the previous design in addition to an improved performance along with a miniaturised dimension.…”

Biomedical telemetry is an emerging field of research which enables the formation of a transmission link from inside a living body to an external device. Implantable medical devices are now one of such valuable advancement in the field of biomedical telemetry. Implantable patch antennas are gaining attention and are becoming more of a choice for implantable medical devices that uses mostly RF telemetry. In this work, a state-of-the-art design for a rectangular implantable flexible patch antenna is proposed. The operation band for the antenna is chosen in the Industrial, Scientific and Medical (ISM) band (2.4-2.4835 GHz). The tiny dimension of the antenna, including the 9.45 μm thickness of the patch itself allows the antenna to be highly flexible and provides excellent results even at extreme bent conditions. For simulation environment, a three-layer human tissue model was used, where the antenna was encapsulated between the fat and skin layer. CST Microwave Studio was chosen to design and simulate the antenna. Several performance parameters were simulated, such as the operating resonant frequency, the return loss, radiation pattern, specific absorption rate and also sensitivity of the antenna when introduced to bending.

Anahtar KelimelerMikroşerit antenler, Implant anten, ISM-bandı, Deri taklit sıvısı, Biyotelemetri Özet: Bu çalışmada, ISM-bandı (Industrial, Scientific and Medical 2.4 − 2.48GHz) tıbbi telemetri uygulamaları için fare derisi içerisinde çalışan yeni bir ekit mikroşerit anten tasarımı sunulmaktadır. Arşimet spiral elemanını temel alan anten tasarımında ışıma elemanı, toprak (GP) destekli dielektrik (Rogers RO3210, ε r = 10.2) tabaka üzerine yerleştirilmiştir. Önerilen mikroşerit ekit anten tasarımının sayısal modellenmesi ve analizi elektriksel olarak fare derisi özelliklerine sahip ortamda (cole-cole modeli, ε f (ω), ρ = 1050 kg/m 3 ) gerçekleştirilmiştir. Çalışmada, ekit anten yapısına ait sayısal analiz ve fare derisi taklit sıvısı içerisindeki ölçüm sonuçlarına yer verilmektedir. Benzerleriyle kıyaslandıgında oldukça küçük boyutlu (r=6 mm) önerilen anten tasarımına ait benzetim ve ölçüm sonuçlarının oldukça uyumlu oldugu gözlemlenmektedir. Ekit anten tasarımına ait sayısal analizler CST Microwave benzetim programı ile elde edilmiştir. Design of A Rat Skin Implantable Microstrip Spiral Antenna for ISM-Band Medical Telemetry Operations and In-Vitro Measurement KeywordsMicrostrip antennas, Implantable antenna, ISM-band, Skin-mimicking gel, BiotelemetryAbstract: In this paper, a rat skin implantable microstrip spiral antenna design for ISM-band medical telemetry operations has been introduced. In the antenna design Archimedean spiral shaped radiation element is placed on to the ground (GP) backed dielectric (Rogers RO3210, ε r = 10.2) substrate. Numerical modeling and analysis of the proposed implantable microstrip antenna design is carried out in a dielectric material having rat skin properties (cole-cole model, ε f (ω), ρ = 1050 kg/m 3 ). In the paper, numerical analysis results of the proposed implantable antenna design along with the corresponding in-vitro measurements are presented.It has been observed that the simulation and measurement results of the implantable antenna design, which is quite small (r = 6mm) compared its counterparts, are reasonably similar. We note that the numerical analysis of the proposed antenna designs have been carried out using CST Microwave Studio.
