This paper addresses the effects of two main microstrip wearable antennas on the specific absorption rate (SAR) on the human trunk as well as their impact performance in terms of gain, efficiency and required area. Rectangular patch and PIFA jeans wearable antennas intended for wireless body area network applications at 2.45 GHz are under analysis. The SAR values averaged over 1 g and 10 g tissue...
Transcutaneous Energy Transfer (TET) is a promising solution to operate implantable mechanical blood pumps such as Left Ventricular Assist Devices (LVAD) without the need for a percutaneous driveline. In order to control the power flow of the wireless energy transfer system and in order to transmit sensor data, a wireless communication channel is needed. This paper describes the design of an implantable...
In this paper, we design and implement a novel six-band frequency reconfigurable Planar Inverted-F Antenna (PIFA) for GSM1800, WCDMA, m-WiMAX and WLAN applications. The antenna consists of three radiator patches whose optimal parameters are iteratively selected on different configurations using Genetic Algorithm (GA). PIN-diodes are used in appropriate locations to accurately control the operating...
