Summary:
A two-PIFA system suited to functioning inside the tablet computer with a complete, metal back cover for 2.4-GHz wireless local area network (WLAN) operation is proposed. The antenna was constructed by stamping a flat plate and bent two times to form a compact structure. The PIFA was fed and short-circuited at the top patch above the antenna ground with a vertical ground wall connecting therebetween. The two PIFAs were symmetrically located on the metal cover and grounded therein. The results showed that comparable Eθ and Eφ fields were obtained for the tablet used in the three major positions, the landscape, portrait, and bottom-down modes.
