In this study, numerical and experimental analysis of a dual band (Medical Implant Communications Service-MICS; 402-405 MHz, Industrial, Scientific and Medical-ISM; 2.4-2.48 GHz) implantable antenna design for biomedical applications are presented. The proposed antenna is in the type of stacked Planar Inverted-F Antenna (PIFA) covered with a superstrate. The antenna has a size of 2 cm x 1 cm x 3.81 mm. Numerical analysis of the implant antenna is carried out using High Frequency Structure Simulator (HFSS) software. The proposed antenna is fabricated and in vitro tested in skin phantom. It is shown that the antenna resonates at 403.5 MHz with a reflection coefficient of -23 dB, and a 10-dB bandwidth of 56 MHz, which covers the MICS band, moreover, it resonates at 2.45 GHz with a reflection coefficient of -22 dB, and a 10-dB bandwidth of 200 MHz, which covers the ISM band. The maximum simulated gain is found as -33 dBi and -13 dBi for MICS and ISM bands, respectively. Communication link measurements are performed using commercially available Microsemi-Zarlink Application Development Kit for Medical Telemetry (ZLE70102) in order to check the functioning of the proposed antenna. Designed antenna is inserted into the MICS band phantom and it is achieved to wake-up base station module at ISM band and to send data at the MICS band in 4 meter range.

Dual band microstrip implantable antenna design for biomedical applications Alptekin, Damla; Gençer, Nevzat Güneri; Alatan, Lale; Department of Electrical and Electronics Engineering (2015) In this study, numerical and experimental analysis of a dual band (Medical Implant Communications Service-MICS; 402 − 405 MHz, Industrial, Scienti c and Medical-ISM; 2.4 − 2.48 GHz) implantable antenna design for biomedical applications are presented. The proposed antenna is in the type of Planar Inverted-F Antenna (PIFA) covered with a superstrate. For miniaturization, the metallic patch of the antenna is meandered and shorting-pin is used between the patch and ground plane. In addition, stacking patch str...
A dual band antenna design for implantable medical devices ALPTEKİN, DAMLA; Gençer, Nevzat Güneri; KUCUKDEVECİ, Fikret (2014-10-17) In this study, design and the numerical analysis of a dual band (MICS (Medical Implant Communications Service; 402-405MHz) and ISM (Industrial, Scientific and Medical; 2.4-2.48GHz)) implantable antenna which is planned to be inserted in the header of the medical device is presented. The proposed medical implantable antenna (MIA) is in the type of planar inverted F Antenna (PIFA). For miniaturization, the metallic patch of the antenna is meandered and a shorting-pin is used between the patch and ground plane...
Cylindrical Microstrip Patch Array Modified Neural Multiple Source Tracking Algorithm Caylar, Selcuk; Dural, Guelbin; Leblebicioğlu, Mehmet Kemal (2008-07-11) In this study Cylindrical Microstrip Patch Array Modified Neural Multiple Source Tracking Algorithm (CMN-MUST) is proposed. CMN-MUST implements previously reported Modified Neural Multiple Source Tracking Algorithm (MN-MUST). CMN-MUST algorithm uses the advantage of directive pattern of microstrip patch elements by considering only a part of array elements for a chosen sector. This reduces neural network sizes and also improves the spatial filtering performance. The proposed algorithm improves MN-MUST algor...
Three Dimensional Microfabricated Broadband Patch and Multifunction Reconfigurable Antennae for 60 GHz Applications Hunerli, H. V.; Mopidevi, H.; Cagatay, E.; Imbert, M.; Romeu, J.; Jofre, L.; Cetiner, B. A.; BIYIKLI, NECMİ (2015-05-17) In this paper we present two antenna designs capable of covering the IEEE 802.11ad (WiGig) frequency band (57-66 GHz and 59-66 GHz respectively). The work below reports the design, microfabrication and characterization of a broadband patch antenna along with the design and microfabrication of multifunction reconfigurable antenna (MRA) in its static form excluding active switching. The first design is a patch antenna where the energy is coupled with a conductor-backed (CB) coplanar waveguide (CPW)-fed loop s...
Dual frequency reconfigurable reflectarray antenna of split ring elements with RF MEMS switches Güçlü, Caner; Aydın Çivi, Hatice Özlem; Akın, Tayfun; Department of Electrical and Electronics Engineering (2010) Dual band (K and Ka) electronically scanning reflectarray with RF MEMS switches is designed, implemented and measured. Unit cell of the reflect array is composed of conductor backed split-ring elements. In order to steer the beam, the phase of the incident circularly polarized wave is controlled by RF MEMS switches that modify the angular orientation of split-rings individually. Reflectarray is designed using unit cell approach with periodic boundary conditions. The antenna is fabricated by using surface mi...
