摘要

A compact uniplanar dual wideband antenna for tablet computers is presented.rnThe proposed antenna provides full coverage of LTE700/2300/2500, GSM850/900/rn1800/1900, UMTS2100, Bluetooth, and 2.4-GHz WLAN bands with a very small foot printrn30 × 10 mm~2. The antenna has uniplanar structure and is easy to fabricate on single side ofrn0.8-mm thick FR4 substrate. This is achieved through three optimized strips: a feedingrnstrip, an inductively coupled inverted L-shaped strip, and a shorted strip embedded withrnSMT components. The proposed design supports more than eight operating bands in 3:1rnVSWR standard, exhibiting positive gains over all nine bands of operation and 80%–90%rnradiation efficiency in the higher LTE and WWAN bands.
