Abstract :
The LTCC (Low-temperature Cofired Ceramics) technique is considered for the metamaterial substrate of a microstrip antenna. The target frequency is 76 GHz~77 GHz for the automotive radar. The metamaterial substrate design and microstirp antenna design are discussed in this paper. The reflection and transmission coefficients of metamaterials are simulated using HFSS simulator. The permittivity and the permeability are calculated from these coefficients. The microstrip antennas are designed with this substrate. The characteristics of antenna on the metamaterial substrate are compared with those of the antennas on the dielectric substrate.
