Monopole antenna integrated with keyboard ground plane in a laptop computer

摘要

A novel monopole antenna integrated with the keyboard ground plane in a laptop computer is presented. The antenna is installed on a notched region (40 mm × 8 mm). The hook-shaped monopole can be combined with the keyboard ground plane to form a coupled-fed loop path to enhance bandwidths. The proposed antenna can be designed to excite several resonant modes of the coupled-fed loop, the hinge slot between the display ground plane and the keyboard ground plane and those of the open slot placed the antenna element. The proposed antenna can cover LTE/WWAN operation in the 824-960 and 1710-2690 MHz bands with good antenna efficiency.
