Executive Summary

There have been many antenna designs studied and developed in 3G mobile phone applications. Multiband operation has become a basic requirement for internal antennas to be used in the mobile phone for wireless communication system. These papers are evaluated the multiband antenna operation for the application in 3G wireless communication systems. In recent years, a 4G system is in development and expected to supply the better quality of data throughput operation. In this paper, a high performance planar antenna with a capacitive tuner as the primary radiator for 4G operation is presented.
