Design of the millimeter wave circularly polarized mircrostrip antenna array

With the development of the new technology and the new materials, millimeter wave microstrip antenna has been focused by more and more antenna researchers in recent years. Based on the cavity mode theory, the circularly polarized microstrip antenna is analyzed and a microstrip antenna array has been designed. The antenna designed in the paper has the advantages of smaller cubage, less weight and easy to be integrated with other microwave components.
