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 compact(More)
Personal wireless communications is a true success story and has become part of people’s everyday lives around the world. Whereas in the early days of mobile communications Quality of Service (QoS) was often poor, nowadays it is assumed the service will be ubiquitous, of high speech quality and the ability to watch and share streaming video or even(More)
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)
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)
This paper discusses an active integrated microstrip antenna with multiple input and multiple output (MIMO) 2×2 element design. The active component as power amplifier is integrated with the rectangular patch antenna for gain enhancement at port 2 and port 4. The feeding technique used is aperture coupled to easily integrate the passive antenna with(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)
Currently, most of implanted medical devices are using inductive coupling for communication, which leads to difficulty in transmitting medical data records for several meters range. In order for the implanted device is able to be used in longer range transmission, the device is wirelessly transmitted in the form of electromagnetic signals. This initiates us(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)
Channel modeling is the starting point of effective, efficient body-centric communications. Specifically, path loss prediction plays an important role in estimation of received signal strength, interference optimization and analysis, link budget design and analysis, and cell size estimation. Path loss models are classified as deterministic, empirical, and(More)
