A bezeless-enabling antenna for ultra-thin tablet computer applications

摘要

A novel antenna for wireless local-area-network (WLAN) applications is presented to enable bezeless antenna-integration to ultra-thin tablet computers. Unlike conventional antennas that require wide plastic-bezels, this 37.5×10-mm antenna sits on the LCD metal frame with a gap of only 3.5 mm. Even with such small gap, excellent RF performance is demonstrated. The efficiency is as high as 83% and the bandwidth is about 100 MHz at 2.4 GHz. This antenna concept may eliminate the long-hated plastic-bezel around the LCD display and improve industrial/mechanical designs of tablet computers.
