Dual-band handset antenna based on multi-branch monopole for LTE/WWAN applications

摘要

A single-feed compact dual-band antenna based on multi-branch monopole structure is proposed for LTE/WWAN handset applications. Its operational principles are illustrated via a series of parametric analyses, showing the origin and characteristic of each of the resonant modes. For verification, a prototype antenna was built, and the measured performance agrees well with those simulated.
