  • Abstract In this thesis, two low-profile planar LTE/WWAN antennas for tablet communication devices are presented. The first antenna is disposed around a ground corner, and the antenna size is 57.5 x 6.5 x 0.8 mm3 only. By embedding an opening in a loop strip, it can be transformed into a dual-branch monopole antenna. By aided with a matching circuit, the antenna can provide two wide operation bands with a planar, low-profile structure, making it promising for applications in modern slim tablet communication devices with a narrow frame. The proposed antenna applied to form a two-antenna array is also studied. A second low-profile planar antenna to be employed along an edge of the tablet device system ground plane is also presented. The second antenna is also a loop strip having an opening, sized 55 x 10 x 0.8 mm3. In the second structure, the opening and the feeding point of the antenna are arranged to be at the same edge of loop strip, which allows the antenna to have two wide operating bands with a low-profile structure because the proposed structure can decrease the coupling between the antenna and nearby ground plane. Both the two antennas in this thesis can cover the 704~960 and 1710~2690 MHz bands for the LTE/WWAN operation.
