在此提出一種能涵蓋LTE、GSM、PCS、DCS、UMTS 等手機頻帶的天線，而該天線多頻帶的特性可由一曲折的L型單極天線結構加上兩個額外的袖型結構來達成。所謂的袖型結構是指由接地面延伸出的微帶線結構，且上述所提及的兩個袖型微帶線結構其線寬皆維持均等長度，而L 型單極天線則是由兩段不同線寬的微帶線所組成，此篇文章所設計的天線藉著依序導入上述的三個結構，進而確立其生成的反射損耗頻帶寬能涵蓋所需的應用頻段。而關於該手機天線的特定吸收率(SAR)的模擬也將在文章中加以討論。

A multi-band antenna covering the LTE, GSM, PCS, DCS, and UMTS bands is presented. It is featured to have a meandered L-shaped monopole with two added sleeves.The two sleeves are extended from the ground plane and are of uniform width. The L-shaped monopole is composed of two sections with different widths. Locations and
widths of the monopole and the sleeves are selected by a step by step observation of the role each element plays on the over performance of the proposed antenna. The SAR performance of the proposed antenna is also investigated.
