Abstract: In order to solve the problems of a conventional flat surface wave generator which has limitations on being applied to a curved structure due to more than a certain required thickness of a dielectric material, proposed are a flexible surface wave generator and system and method for surface wave communication using the same where the flexible surface wave generator is bendable by removing a third dielectric material and by making a first and a second dielectric material thin and at the same time reaches communication performance applicable to the ISM band by changing a pattern of a surface wave generation member and by forming a slit in a radiator material, so it is possible to easily establish a surface wave communication system even in environments where a conventional flat surface wave generator is difficult to be applied by being tightly attached to the surface of a metal medium with curvature.
