Abstract
In this paper, a frequency tuning method for an U-shaped slot antenna for long term evaluation (LTE) wireless communication devices is presented and the performance of the antenna (return loss, total and radiation efficiencies…etc) is reported. The lower operating frequency of the antenna (700 - 960 MHz) is switched with different inductor loadings from 110 nH to 30 nH. The inductor component loads the U-slot antenna and thus enables to tune the frequency of low band (700 - 960 MHz). Higher bands (1710 - 2700 MHz) of the antenna remain unchanged with different inductor loadings. The impact of the inductor position is also investigated and the results are reported. The antenna presented in the paper is comparable with that of Cho-Kang Hsu’s publication. However, in Chos publication, only one low band is covered. In our design, all of existing commercial LTE frequency bands (Band 17 - Band 7) used in typical mobile devices are covered by the proposed antenna.
