The Laser Interferometer Space Antenna project (LISA) is a co-operative program between ESA and NASA to detect gravitational waves by measuring distortions in the spacetime fabric. LISA Pathfinder is the precursor mission to LISA designed to validate the core technologies intended for LISA. One of the enabling technologies is the micro-propulsion system necessary to achieve the uniquely stringe...

A multiband Fractal Koch dipole textile antenna is proposed for wearable applications. The antenna is designed to operate at 0.9 GHz, 2.45 GHz and 5.8 GHz. Denim materials as the substrate are selected aiming to obtain robustness, flexibility and a lightweight textile antenna. The antenna model is designed, simulated, optimized and analyzed using Microwave Studio CST software. Two types of mult...

Screen-printed and inkjet-printed conductive fabric antennas have been investigated in this manuscript. The former showed optimal radiation performance after fabrication measurement, which was the basis for developing a new antenna feeding technique. aperture-fed technique is achieved with single coaxial cable overlayed on cut-out slot ground layer of patch antenna. connected silver-based epoxy...

The Internet of Things (IoT) scenario is strongly related with the advance of the development of wireless sensor networks (WSN) and radio frequency identification (RFID) systems. Additionally, in the WSN context, for a continuous feed, the integration of textile antennas for energy harvesting into smart clothing is a particularly interesting solution when the replacement of batteries is not eas...

We investigate here a number of variations of the Para-IRA, which is an Impulse Radiating Antenna configured for parachute delivery. We consider first two scale models of the Para-IRA with aluminum reflectors, and then we consider a full-scale version built from fabric. In the scale models, we first investigate the effect of using a large F/D ratio in an IRA. We then investigate the effect of u...

A wearable low-profile inset-fed quarter-wave folded microstrip patch antenna for noninvasive activity monitoring of elderly is presented. The proposed antenna is embedded with a sensor-enabled passive radio-frequency identification (RFID) tag operating in the ultra-high frequency (UHF) industrial-scientific-medical (ISM) band around 900MHz. The device exhibits a low and narrow profile based on...

There has been a tremendous rumble in UWB research after the U.S. Federal Communications Commission (FCC) allocated a frequency range with a bandwidth of 7.5 GHz from 3.1–10.6 GHz for UWB applications. Ultra wideband (UWB) technology was earlier limited to special applications, primarily in the military area and there primarily to electronic warfare. The antennas were usually horn antennas or m...
