基于新型体积再利用技术的一种多频带手机天线设计

本文提出了一种通过开阻抗调谐槽的方法实现对移动终端天线有限体积多次利用的新型体积再利用技术.该技术在保持天线体积不变的前提下，利用开缝技术调谐等效电容、电感，使得天线在工作需要的多个频点产生谐振，实现多频带.利用这种技术，设计并加工制作了一款工作在GSM, DCS, PCS, WCDMA频段的内置手机天线并进行了测试.结果表明，该天线在其工作频带内阻抗匹配良好，辐射效率高.且该多频PIFA天线的体积只和传统双频PIFA天线的体积相当，实现了天线小型化.实验测试结果和仿真结果一致，证明了这种新型体积再利

Designof multi-band mobile handset antenna based on novel volume reuse technique

This paper presents a novel technique to reuse the finite volume of mobile handset antenna that based on the input impedance tuning slot method. The proposed technique makes equivalent capacitances and inductances by properly tuning slots to achieve the aim of generating multi resonances in the allocated volume. Under the proposed technique, an internal mobile phone antenna for GSM, DCS, PCS and UMTS operation has been designed and fabricated. Results show that the antenna has multiband and wideband performance as designed. Besides, the efficiency results show that the antenna provides high efficiency across the entire operating bands. Also, the antenna has a small size merely comparable to traditional dual band PIFA antenna. The proposed technique has been validated by simulations and measurements of the recommend antenna.
