A novel internal quad-band planar inverted-F antenna (PIFA) for oval-shaped mobile phones is presented. The particular shape of the proposed PIFA patch is an oval with several slits. These slits separate the patch into two resonant paths, generating two bands of about 900 and 1800 MHz. The obtained bandwidth covers GSM850 (824-894 MHz), GSM900 (880-960 MHz), DCS1800 (1710-1880 MHz), and PCS1900 (1850-1990 MHz) bands. Details of the proposed antenna design and experimental results are presented and discussed.
