SUMMARY This paper presents a realization of a simple antenna system for land vehicle satellite communication that is tested in experiments conducted on the Engineering Test Satellite-VIII (ETS-VIII). The developed antenna system which was mounted onto a vehicle roof is compact, light weight with simple satellite-tracking operation. In order to realize(More)
This paper provides a dual-arm modified-spiral magnetic-type textile antenna for wireless medical communication applications. The proposed antenna is constructed of a woven fabric substrate and a copper patch on the substrate aiming at 2.45 GHz band operation. The antenna is simulated and measured with and without human body phantom. The antenna shows(More)
SUMMARY This paper presents a simple antenna system for land vehicle communication aimed at Engineering Test Satellite-VIII (ETS-VIII) applications. The developed antenna system which designed for mounting in a vehicle is compact, light weight and offers simple satellite-tracking operation. This system uses a microstrip patch array antenna, which includes(More)
We are developing a microwave imaging system that is affordable, easy to operate (portable), non-ionization (safe radiation) and non-invasive. In this paper, a microwave imaging system using UWB printed dipole-like antenna based on back-projection algorithm is proposed at frequency of 5.8 GHz aimed at tumor imaging system in order to obtain a reconstructed(More)
— Nowadays, implanted medical devices that are using inductive coupling for communication, cannot be used for transmitting medical data in several meters range. This triggers us to study about implantable device systems in order for communications is enabled to be longer range by transmitting wirelessly electromagnetic signal. In this system, the external(More)
This paper provided a measurement campaign of simple antenna system mounted on a vehicle by utilising a Japanese geostationary test satellite called Engineering Test Satellite VIII (ETS-VIII). We developed an antenna system that was compact, light weight, and promising in low cost production. The antenna system was built by a 16-cm patch array antenna,(More)
—This paper proposes a rotary phased array head coil owing to the phased array coil advantages for rapid imaging with parallel processing and reducing image artifact due to its larger field of view. The array coils consist of eight coils, where each coil is designed from four wide conductor sheets and four small conductor sheets onto which combined with(More)
Receiver radio frequency coil (RF coil) is one of the important components in MRI system, which it operates by receiving RF signal that emitted from the excited body part. In this paper, a novel design of dual resonant RF phased array coil for MRI 3T and 7T system is proposed. Phased array is chosen due to its advantages for parallel imaging, high SNR and(More)
