Introduction Owing to their advantages of low profile and compact size, designs of the planar inverted-F antenna (PIFA) for achieving GSM/I>CS dual-band operations for mobile phones have recently received much attention. Many related designs have also been reported in the open literature [1]-[4]. For operating in the 900 and 1800 MHz bands, these designs usually generate only one resonant mode for each operating band, which leads to limited bandwidths for the operations of the CiSM (890-960 MHz) and DCS (1710-1880 M
