Abstract
Cracks in metal can be produced by many factors, such as external loads, physical processes, and chemical processes, such as alkali and corrosion. Structure health monitoring (SHM) is very important in maintaining the reliability of a building. Considering that the ultimate goal of a building health monitoring system is to provide sensory information that can facilitate decision making regarding the feasibility of components. Microstrip antennas have been shown to be able to detect cracking in metals according to their characteristics. In this paper will discuss the capability of a microstrip antenna with a circular patch having dual frequency operation to detect crack in metal.
