摘要：

A novel compact dual-band loop-slot combination antenna for use in wireless local area network (WLAN) applications is proposed. The radiation mechanism is based on two resonant structure types, metal loop and slotline, combined into a single antenna to achieve WLAN 2.4 (2.4 similar to 2.484 GHz) and 5 GHz (5.15 similar to 5.85 GHz) operation. The proposed antenna is implemented in an ultra-thin tablet computer of dimensions 241 x 183 x 6.5 mm(2), with a fully metallic cover on the bottom. The size of the proposed antenna is only 21 x 7.5 x 4.5 mm(3) with a metal bottom cover below and an LCD panel nearby. The reflection coefficient measured from the antenna demonstrates that the operation bandwidth is 140 and 1300 MHz using a -10-dB definition in WLAN 2.4 and 5-GHz bands, respectively. In addition, good radiation performance is also achieved.
