Abstract :
A compact inverted-F antenna with multiband operations for LTE, WWAN, WiMAX and WLAN applications is presented. The antenna consists of multi-branch strips and is fabricated on both sides of the ceramic substrate, which has a compact size of 90(L)×10(W)×0.5(T) mm3 to be embedded inside an ultra-thin laptop computer as an internal antenna. Three operating bands covering 673-993 MHz, 1673-3153 MHz and 3316-3603 MHz for the LTE700/2300/2500, WWAN, WiMAX (2.3/2.5/3.5 GHz) and WLAN (2.4 GHz) systems are achieved with good radiation efficiencies.
