Abstract :
A multibranch inverted-F antenna with multiband operations for long-term evolution (LTE), pentaband wireless wide area network (WWAN) and IMT-E (2.6 GHz) applications is presented. The antenna consists of multibranch strips and is fabricated on a direct bond copper (DBC) substrate, which has a compact size of 96 (L) × 11.2 (W) × 0.5 (H) mm3 to be embedded in the laptop computer as an internal antenna. Three operating bands covering 663-993, 1689-2190, and 2449-2783 MHz for the LTE, GSM850/900 and DCS/PCS/UMTS, and IMT-E systems are achieved with good radiation efficiencies. The proposed antenna can be embedded in the laptop computer for the LTE, WWAN, and IMT-E applications.
