Mobile e-coli Detection Using Microwave Technique

Abstract

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 reduce the physical size of probe by immersing and transmitting antenna, receiving antenna, and target into a high dielectric constant material, which is water. Here, we observed the effect of temperature changes with dielectric constant for E-coli growth. A novel rectangular patch antenna is designed and presented to detect the Mobile E-coli bacteria. The result shows that as the temperature of water increase, the survival of E-coli bacteria is prolonged until one limit of temperature.
