摘要

A very small antenna for full metal housing (FMH) tablet that can providernGPS and WLAN 2.4/5.2/5.8 GHz operations is presented. This miniaturized antenna isrnformed by a loop strip of about 41 mm with its end terminal connected to the ground viarnan inductor, and its front section capacitively coupled to a feed strip. Except for the antennarnself-resonant modes (loop modes); two cavity modes are also involved to realize multibandsrnoperation, which is a novel technique for antenna design in FMH devices. Here, thernthree loop modes are at 1.575 GHz, 5.2 GHz, 6 GHz, and the two cavity modes are atrn2.45 GHz and 5.4 GHz. The measured efficiencies at 1.575, 2.45, and 5.5 GHz were 36%,rn79%, and 78%, respectively. Because the loop strip is only 0.18λand in meander line shapernat GPS frequency, the planar dimension of proposed antenna can be reduced to 10×rn8 mm~2 . Therefore, the proposed antenna has very competitive size for applications in thisrnoperation environment.
