We present a miniaturized antenna applied for biomedical applications. The key to communicate with the external devices is the antenna design. Meanwhile, a multilayered PIFA antenna operating at 433MHz industrial, scientific and medical (ISM) band with the gain of −28dBi is proposed. In antenna simulation, we simulate the antenna inside capsule system composed of capsule shell, and circuit equivalent...
Antennas are important components of Wireless Capsule Endoscope (WCE) that has been explored due to its non-invasive nature compare to the traditional endoscopy. The main challenges of these antennas include data rate of the telemetry system, miniaturizing the capsule, propagating efficiency of the antenna in the vicinity of human body. In this paper, a miniature Ultra-wideband (UWB) antenna is proposed...
A compact implantable planar inverted-F antenna with the full ground plane is presented for bio-telemetry applications in the medical device radiocommunications service (MedRadio) band (401–406 MHz). A basic three layer phantom model of skin, fat and muscle is initially considered and the antenna is placed in the muscle layer. Later, Gustav voxel model is used to verify the design. The overall size...
This paper describes a flexible loop antenna for in-body applications. This antenna works in the Med Radio band(402 MHZ–406 MHZ) which is the standard band for Bio Implantable applications, ISM Bands at 433 MHZ“434.8 MHZ and 902 MHZ“ 928 MHZ. The antenna is having a size of a 3.5 mm radius and height of 15 mm. The simulated antenna is having a Bandwidth of 228 MHZ (310 MHZ–538 MHZ) at 400 MHZ and...
In this paper, a flexible loop implantable antenna is proposed for in body applications. The proposed antenna covers the Med Radio band (401–406MHZ) which is the standard band for Bio Implantable applications, ISM bands at 433–434.8MHz and 902–928MHz. The antenna is made of biocompatible loss free polyamide hollow cylindrical substrate of relative permittivity 3.5 having a size of 3.3 mm radius, height...
An inverted-F antenna with meandered line is characterized in this paper in terms of its proximity to the human body. Radiation characteristics are simulated and analyzed in the context of proximity of the antenna to human body tissue. The dependence of radiation characteristics like radiation pattern, resonant frequency, radiation efficiency, gain and front-to-back ratio; on the type & dimensions...
The goal of this paper is to introduce a statistical approach for modelling antennas behaviour in the vicinity of the human body. A very preliminary model based on geometrical optics has been developed, and calculations have been performed for parallel and perpendicular polarisations, for 0.915, 2.45 and 5.8 GHz, for various human body tissues, and for several antenna locations on the body. The statistics...
