本論文提出一項具有輻射型耦合饋入的手機天線，藉由輻射型耦合饋入技術，可以有效地將傳統耦合饋入迴圈天線與耦合饋入短路單極天線整合在本天線架構中，並且分別激發寬頻的共振模態以涵蓋GSM850/900/1800/1900/UMTS/LTE2300/2500七個頻帶之所需。此外，藉由與突出接地面的緊密整合，使得本天線在實際應用時，得以在手機內部裝置更多的電子元件。而為了探討本天線的近場輻射特性，本論文也進行了一系列SAR及HAC的模擬測試與分析。

A mobile phone antenna with a radiating coupling feed is presented. By using the radiating coupling feed, the conventional coupled-fed loop antenna and coupled-fed shorted monopole antenna can be efficiently incorporated into the antenna structure and respectively excite a wide band resonant mode to cover GSM850/900 and GSM1800/1900/UMTS/LTE2300/2500 for the seven-band operation. Besides, the antenna can be in compact integration with the extended ground plane such that more electronic components in the mobile phone can be accommodated in the practical applications. In order to study the near-field radiation characteristics of the antenna, SAR and HAC are also simulated and analyzed.
