TUNABLE CIRCULAR POLARIZATION MICROSTRIP ANTENNA USING PLATES LOADING

摘要

PURPOSE: A tunable circular polarization microstrip antenna is provided to control the effective length of the microstrip antenna by adjusting the respectively loaded plate. CONSTITUTION: A dielectric body has the predetermined dielectric constant. The ground plane(100) is located under dielectric body. The ground plane performs the grounding function. A radiation element(200) is located from the ground plane in the prescribed distance. The feeding point is formed in the center of the radiation element. The radiation element has a folded structure.
