With advances in technology and machinery manufacturing technology, the satellite navigation system plays a more and more important role in the modern society. People demand increasingly for satellite navigation. Satellite navigation is increasingly used in military systems, so military and civilian value is higher and higher. For the satellite signal reception, microstrip antenna plays an indispensable role. As the mechanical design of microstrip antenna is simple, easy manufacture, low cost, smaller size, lighter weight, with the overall unity of active devices and integrated circuit, etc. The successful development of high dielectric constant ceramic material enables the area of microstrip antenna to narrow several times. Microwave dielectric ceramics material has some merits such as high dielectric constant, thermal stability and excellent characteristics of small dielectric loss. Different dielectric constant substrate can be prepared through changing and doping modification of process parameters, including the relative dielectric constant of microwave dielectric ceramics for more than a few dozens which can be used for different microwave frequencies. Those are important reasons for promoting the development of microstrip antenna.
