Abstract
The invention relates to a stacked circularly polarized antenna structure (). The stacked circularly polarized antenna structure () comprises a first antenna (), a second antenna (), and an adhesive element (). The adhesive element () is adhered between the first antenna () and the second antenna () to stack and form a stacked circularly polarized antenna structure () having the first antenna () and the second antenna () made of ceramic material with the same dielectric constant, having two feeding elements to reach circular polarization and enhance antenna bandwidth, and stacking the two antennas () together to form two resonance frequencies.
