In this study, an all-planar penta-band antenna for laptop applications is presented. This antenna is placed parallel to the upper edge of the laptop panel (300 x 200 mm(2)) with a restricted available space (120 x 10 x 0.4 mm(3)) The antenna is mainly composed of two back-to-back strip-loaded slit antennas with different sizes and a T-shaped feeding network. Each strip-loaded slit antenna has two resonances, respectively provided by the metal strip and the slit. The measured 6-dB return loss bandwidth covers the GSM850/900/DCS/PCS/UMTS. Over the GSM850/900 and the DCS/PCS/UMTS bands, the average gains in the H-plane are about 2.06 dBi and 0.02 dBi, respectively. Good antenna features and the planar configuration make the proposed antenna attractive for ultra-thin laptop applications.
