Abstract
This work describes a novel small-size monopole antenna with eight-band LTE/WWAN operation in tablet computers by introducing a G-shaped driven monopole strip. The subsequently obtained impedance bandwidths across dual operating bands approach 264/1046 MHz at the LTE and WWAN bands, respectively. Given that the overall antenna size is only 35 ×10 ×0.8 mm 3 , the proposed planar monopole antenna provides more than 40% reduction in antenna size over that of the conventional ones. Additionally, the measured peak gains and antenna efficiencies are approximately 3.6/5.2 dBi and 67/70% for the LTE/WWAN bands, respectively. Moreover, the proposed planar compact antenna can be deposited inside the tablet computer and fulfills the body specific absorption rate (SAR) requirement (for 1-g body tissue) for mobile device applications.
