The effects of Metallic Loop-Like accessory worn on the human body on SAR at 2.45 GHz
(EDP Sciences, 2017)
This paper presents the Specific Absorption Rates (SAR) in the human body with a monopole antenna. The distance between the antenna and the body were varied at different distances. The parameters (εr, σ) used in the human ...
Compact Microstrip-Based Textile Antenna for 802.15.6 WBAN-UWB with Full Ground Plane
(Hindawi Limited, 2019)
The paper presents the design and investigation of a flexible all-textile antenna operating in the wireless body area network (WBAN) ultrawideband (UWB) specified by the IEEE 802.15.6 standard. The proposed antenna features ...
Dual Band Planar Inverted F Antenna (PIFA) with L-Shape Configuration
(EDP Sciences, 2017)
One of the most used antennas in mobile devices is planar inverted F antenna (PIFA). PIFA can be design in dual band frequencies due to the coverage of the wireless service in a mobile device that requires a multiple ...
Design of single layered circular and rectangular U-slotted, CPW-fed antennas and arrays for RFID applications
(Institute of Electrical and Electronics Engineers (IEEE), 2010-05-26)
This work describes the design of high gain, U-slot antennas for RFID 915 MHz (902-
928 MHz) applications. Four types of antenna were designed, optimized and evaluated -
a circular, U-slotted antenna, a rectangular ...
A smart wearable textile array system for biomedical telemetry applications
(Institute of Electrical and Electronics Engineers (IEEE), 2013)
A smart wearable textile array system (SWTAS) with direction of arrival (DoA) estimation and beamforming is proposed and developed for biomedical telemetry applications. This conformal system enables effective and continuous ...
Parametric studies of the pyramidal microwave absorber using rice husk
(Institute of Electrical and Electronics Engineers (IEEE), 2010)
Agriculture waste has potential to be used as an alternative material for the microwave absorber used in the anechoic chamber. Compared to the current materials used, such as polystyrene and polyurethane, agricultural waste ...
Reflection loss performance of hexagonal base pyramid microwave absorber using different agricultural waste material
(Institute of Electrical and Electronics Engineers (IEEE), 2010-11-08)
Hexagonal base pyramid microwave absorber is the new design of microwave absorber. In this work, two sub-shapes are considered to compare it reflection loss performance. The shapes are hexagonal and truncated hexagonal ...
A novel 2.45GHz switchable beam textile antenna (SBTA) for outdoor wireless body area network (WBAN) applications
(EMW Publishing, 2013)
A novel switchable beam textile antenna (SBTA) for wireless body area network (WBAN) applications is proposed. The SBTA is centrally-fed by a coaxial probe and the power distributed over four circular radiating elements. ...
