Abstract
A polarized antenna with reduced size includes a substrate, a ground electrode, a radiation electrode and a side-feeding electrode. The substrate is made of dielectric materials, and the ground electrode, the radiation electrode and the side-feeding electrode are made of electrically conductive materials. By forming a plurality of characteristics-setting elements within the radiation electrode, the polarized antenna can have the advantages of wider bandwidth and smaller size. By changing the design of characteristics-setting elements, the circular polarization characteristics of the antenna can be adjusted or a linear polarization antenna can be obtained. The present invention can be implemented to become a through-hole device or an SMD device.
