摘要
A novel dual-band wearable compact antenna for the Global Positioning System (GPS) and Universal Mobile Telecommunications System (UMTS) is presented.The proposed antenna pattern is connected to the ground plane vertically and consists of a folded inverted-F connected to two folded branches and a parasitic coupling arm. The measured antenna gain and radiation efficiency of the dual-band antenna are 2.84 dBi/55.14 % and 3.05 dBi/94.08 % for the low band and high band, respectively. With a supporting sponge on the shielding ground, 1-g average specific absorption rate (SAR) is decreased significantly to only 1.38 W/kg to comply with the linking power budget (21 dBm) for the UMTS band. Therefore, the proposed wearable compact dual-band antenna is suitable for wearable device applications. (c) 2012 Wiley Periodicals, Inc.
