An inverted-F antenna with multiband operations for Long-Term Evolution (LTE700/2300/2500), wireless wide area network (WWAN), GPS, WiMAX (2.3/2.5/3.5 GHz), and WLAN (2.4 GHz) applications is presented. The antenna consists of multibranch strips and is fabricated on both sides of an Al(2)O(3) ceramic substrate, which has a compact size of 97 (L) x 11.2 (W) x 0.5 (T) mm(3) to be embedded inside the laptop computer as an internal antenna. Four operating bands covering 646-983, 1503-1589, 1696-2963, and 3396-3646 MHz for the LTE, WWAN, GPS, WiMAX (2.3/2.5/3.5 GHz) and WLAN (2.4 GHz) systems are achieved with good radiation efficiencies.
