Abstract

A internal planar mobile device antenna having a small size of 16×42mm² for the WWAN/LTE operation. The antenna comprises a wandering driven strip at the front side of the substrate and an invert F shape parasitic shorted strip at the back. The driven strip generates λ/4 and 3λ/4 resonant modes. An extra resonant at 1800MHz is obtained and the bandwidth of the driven strip´s two resonant modes is enhanced by embedding the parasitic shorted strip. Owing to the contribution of the two strips, the antenna capable of two wide bands (780-1090/1700-2850 MHz) to cover the desired GSM850/900/1800/1900/UMTS/LTE2300/2500 bands for the WWAN/LTE operation. Details of the proposed antenna and its radiation performances are presented.
