Abstract
A dielectric dual antenna apparatus intended for applications such as small-sized radio frequency devices. The dual antenna comprises a first partial antenna which implements the lower operating band of the antenna and another partial antenna implementing the upper operating band. The partial antennas have a shared substrate, which together with the radiators constitutes an integrated antenna component. The matching of the dual antenna can be improved in either operating band without degrading it in the other operating band at the same time. Methods of operating the aforementioned apparatus are also disclosed.
