“…The system typically operates in the sleep mode until it receives a wakeup signal at the (2.4 -2.48 GHz) Industrial, Scientific, and Medical (ISM) band after which it starts transmitting the data wirelessly at the MICS band. To meet such requirement of operating in two frequency bands, different kind of dual-band implantable antennas were proposed in [13]- [17]. The top view snapshots of the antenna prototypes in [13]- [17] are shown in Fig.…”

“…A differentially-fed dual-band implantable antenna can be easily connected with differential circuitries that can eliminate the loss introduced by baluns and matching circuits [16]- [17]. In [16], the differentially fed implantable antenna was designed to operate at two close frequency bands (MICS band and 433 MHz ISM band).…”

“…Biyotelemetri sistemlerinin önemli bileşenlerinden biri olan * İ lgili yazar: mhbucar@kocaeli.edu.tr anten elemanı, verilerin iletilmesini saglarken, sistemin küçültülmesinde de oldukça kritik bir rol oynamaktadır. Bu kapsamda, geliştirilecek anten elemanının biyotelemetri sistemlerinin gereksinimlerini karşılayacakşekilde minyatür boyutlu ve biyo-uyumlu olarak tasarlanması biyotelmetri sisteminin başarımı açısından oldukça önemlidir [3,[6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25].

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.

This paper proposes a differentially fed metal frame antenna for biomedical smartband applications. It occupies a planar area of 40 × 20 mm, operating at 2.45‐GHz industrial, scientific, and medical band. The proposed antenna is composed of an external metal frame and an internal metal box acting as ground for electronics. Through a differential feeding to two copper strips located between the metal frame and the metal box, a rectangular ring slot is excited with common mode suppression capability. The antenna prototype is designed in free space, and then adapted to on‐body scenario for both repeater and transmitter cases. Additionally, the proposed differential feeding is modified to the traditional single port, demonstrating the half‐size miniaturization technique. Finally, the simulated results are verified by measurement. The proposed antenna's simple structure and satisfactory performance makes it a perfect candidate for future medical smartband applications, monitoring the physiological parameters of humans for health‐care purposes.
