Abstract

A seven-band WWAN/LTE mobile handset antenna is presented. The antenna structure is small and simple; its dimensions are 115×60×0.8 mm3 where the antenna portion is 15×60 mm2 and the ground portion is 100×60 mm2. The proposed antenna is composed by a directed-fed monopole and two coupled strips. With the combination of the direct-fed monopole and two coupled strips, two wide operating bands for WWAM/LTE can be obtained. The first wideband obtained cover GSM850 (824-894 MHz), GSM900 (880-960 MHz) and is produced by the directed-fed monopole. The second wideband goes from 1710 MHz to 2690 MHz, covering DCS (1710-1880 MHz), PCS (1850-1990 MHz), UMTS (1920-2170 MHz), LTE2300 (2300-2400 MHz) and LTE2500 (2500-2690 MHz), is caused by the introduction of the coupled-fed strips on the antenna. The proposed antenna with simple structure and good performance is a good candidate of mobile phone antenna.

单极型天线与两个耦合带移动电话应用

提出了一种七波段WWAN/LTE手机天线。天线结构小巧简单;其尺寸为115×60×0.8 mm3，其中天线部分为15×60 mm2，接地部分为100×60 mm2。该天线由一个定向馈电单极子和两个耦合带组成。将直馈单极子与两个耦合带相结合，可以获得两个用于WWAM/LTE的宽工作频带。获得的第一个宽带覆盖GSM850 (824-894 MHz)， GSM900 (880-960 MHz)，由定向馈电单极子产生。第二个宽带从1710 MHz到2690 MHz，包括DCS (1710-1880 MHz)， PCS (1850-1990 MHz)， UMTS (1920-2170 MHz)， LTE2300 (2300-2400 MHz)和LTE2500 (2500-2690 MHz)，这是由天线上引入耦合馈电带引起的。该天线结构简单，性能优良，是手机天线的理想选择。
