A linearly‐polarized, planar inverted‐F antenna (PIFA) embedded inside a large‐sized tablet computer with a complete, metal back cover for global positioning system and global navigation satellite system operations is proposed. The antenna was constructed by stamping a flat plate and bent two times to form a compact structure with dimensions 6 × 9 × 50 mm 3 . The patch PIFA was fed and short‐circuited at the top patch above the antenna ground with a vertical ground wall, connecting there between and facing the interior of the tablet. This wall can be used to alleviate the electromagnetic interaction between the antenna and the conducting components in the vicinity. Effects of various antenna locations on the right‐hand circularly‐polarized and the left‐hand circularly‐polarized patterns were also analyzed. Detailed design and the results, thereof, are described and discussed in the article. © 2015 Wiley Periodicals, Inc. Microwave Opt Technol Lett 57:149–153, 2015
