摘要

A new multi-band antenna of the mobile handset with a special structure for the wireless communication applications is introduced, where the intrinsic slots between metal frame and the metal ground of the handset is taken as the main structure of the handset antenna, and the slots are fed by a tapered strip and two thin open-end strips with different lengths. Good performances of the proposed antenna are obtained by using this simple structure. The measured results of the RL and efficiency are presented. The good agreement is also achieved between the measurement and the simulation. No matter in the performances of the antenna, or in the occupied area, the proposed antenna would have a valuable application in handset for the metal frame structure.
