A novel and broad quad‐band planar inverted‐F antenna (PIFA) for cellular/PCS/UMTS/DMB applications is proposed. The proposed antenna consists of the main patch with a slant slit and L‐shaped patch, occupying a total volume of 15 × 44 × 8 mm 3 . The triple resonant frequencies are obtained by changing both the length and width of a slant slit on the main patch and a position of feed line. A broadband characteristic is achieved by optimizing not only the length and height of the L‐shaped patch, but also the length and width of the slant slit on the main patch, which is excited by the modified CPW‐fed antenna. Good broadside radiation patterns with reasonable gains are achieved for all four‐frequency bands of interest. © 2005 Wiley Periodicals, Inc.
