This paper presents the design of the spiral antennas with metamaterial. It is a new way of producing a low-profile and wide-band antenna. According to the relationship of spiral antenna's active region and frequency, a circumferential multilayer substrate is designed with a reduced antenna total height. Based on effective media theory, circumferential multilayer substrate is implemented with aligned disk lattice. Simulation results demonstrated that the novel spiral antenna has relatively high gain, while S_11 of the spiral antenna with metamaterial is not as good as expected.
