Monopole-type antenna with two coupled strips for mobile phone application

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.
