Leaky-wave antenna in multilayer structure for sensor applications

A leaky-wave antenna has been analyzed and designed for application in smart motion sensors. The application of multilayer structure with a thin laminate layer allows for manufacturing the required capacitive elements without the need for SMD components' application. The theoretical expressions are derived allowing for initial unit cell design. The designed antenna structure consisting of 30 unit cells has been designed and verified electromagnetically. Finally the model of the antenna has been manufactured and measured.
