Abstract
A multiband dipole antenna solution suitable for use in various wireless device applications, and methods of tuning and utilizing the same. In one embodiment, the antenna is adapted for use in long term evolution (LTE or LTE-A) radio devices. In one implementation, the antenna comprises (i) two planar directly fed radiating elements operating in a lower frequency band and disposed on two opposing sides of a dielectric structure, and (ii) two electromagnetically coupled radiating elements operating in an upper frequency band also disposed on the opposing sides of the dielectric structure. An additional pair of electromagnetically coupled radiator elements is utilized to achieve wider antenna operating bandwidth.
