| Abstract | A coupled-fed planar PIFA (planar inverted-F antenna) operated in its one-eighth wavelength (λ/8) mode, different from the traditional one-quarter wavelength (λ/4) mode, as the fundamental mode for mobile phone application is presented. The proposed PIFA comprises two radiating strips, both of slightly different lengths and close to about λ/8 at 900 MHz. By incorporating the use of the coupling feed, a wide operating band formed by the two λ/8 modes is excited at about 900 MHz for the antenna to cover GSM850/900 operation. Two λ/4 modes are also generated at close frequencies to from a wide operating band centered at about 1950 MHz to cover GSM1800/1900/UMTS operation. The proposed antenna hence can cover GSM850/900/1800/1900/UMTS penta-band operation for application in the mobile phone. In addition, the antenna has a simple structure and can be printed on a thin FR4 substrate of size 1.6 × 7 × 40 mm3 as a surface-mountable chip antenna. Details of the proposed antenna are presented and discussed. © 2009 Wiley Periodicals, Inc.
