A novel antenna with a small nonground area for mobile phones

摘要

An antenna with a small nonground portion for mobile phones are designed. With the lumped elements and optimized structure, the proposed antenna can cover octa-band applications. Meanwhile the simulated S parameters and radiation patterns can meet the demand. In addition, the structure is capable of being used for the metal frame configuration and forming a narrow frame antenna. Hence, it is a promising candidate for mobile phone applications.
