摘要
A compact uniplanar dual wideband antenna for tablet computers is presented. The proposed antenna provides full coverage of LTE700/2300/2500, GSM850/900/1800/1900, UMTS2100, Bluetooth, and 2.4-GHz WLAN bands with a very small foot print 30 x 10 mm(2). The antenna has uniplanar structure and is easy to fabricate on single side of 0.8-mm thick FR4 substrate. This is achieved through three optimized strips: a feeding strip, an inductively coupled inverted L-shaped strip, and a shorted strip embedded with SMT components. The proposed design supports more than eight operating bands in 3:1 VSWR standard, exhibiting positive gains over all nine bands of operation and 80%-90% radiation efficiency in the higher LTE and WWAN bands.
