Throughout this paper, a newly ultrawideband antenna (UWB) is designed to observe its performance in different medium. The medium used in this study are water and free-space. In free-space a comparison will be done on antenna without casing and with casing. The casing is made of polyamide. A comparison also will be made with antenna with casing in water. UWB antenna is well known as the antenna that...
A high gain reconfigurable narrow beam steering array (RNBSA) antenna with Micro-Electro-Mechanical-System (MEMS) is presented in this paper. The RNBSA antenna is implemented a probe coupling feed technique to supply the energy to the radiating elements from the source and vice versa. At the same time, the MEMS circuits are integrated on the transmission line of the RNBSA antenna as the RF switches...
A reconfigurable MEMS beam steering array (RMBSA) antenna for smart radar application is proposed. The RMBSA antenna is designed with a coaxial probe technique as the medium to feed the current to the centre of the RMBSA antenna before the current is shared out to the radiating elements. This research successfully invented beam steering capability by using Micro-Electro-Mechanical System (MEMS) as...
Escherichia coli detection in different types of water is proposed in this paper. In this study, a theoretical investigation has been carried out to determine the relation between temperature and dielectric constant of different types of water with the growth of E. coli bacteria in each water. Both dielectric constant and temperature plays and important roles in this study. The basic principle of...
Detecting the Survival of E. coli Bacteria in Different Types of Water Using Microwave Technique is proposed. In this paper, theoretical investigation has been carried out to determine the relation between dielectric constant of different types of water with the life of E. coli bacteria in all water and analyze them. The basic principle is to monitor the wavelength of radiation and reduce the physical...
A Prompt and Mobile (In-Situ) E-coli Detection Using Microwave Technique is proposed. In this paper, theoretical investigation has been carried out to determine the importance of microwave technique for detection of E-coli bacteria. We choose this type of bacteria to study their viability at different temperatures from 20° to 40°C. The basic principle is to monitor the wavelength of radiation and...
