An internal quad-band printed monopole antenna for oval-shaped mobile phone applications is presented. The appearance of the proposed antenna is an oval, and the antenna occupies a compact area of the upper part of the oval system ground plane. The printed monopole antenna has two branches, which generate two bands at about 833 MHz and 1820 MHz. The obtained bandwidth covers GSM 850 (824-894 MHz), GSM 900 (880-960 MHz), DCS 1800 (1710-1880 MHz) and PCS 1900 (1850-1990 MHz) bands. Details of the antenna design and results are presented and discussed.
