An Internal Quad-Band Printed Monopole Antenna for Oval-Shaped Mobile Terminals

摘要

An internal quad-band printed monopole antenna for oval-shaped mobile phone is presented. The antenna occupies a compact area of the upper part of the oval-shaped ground plane. The printed monopole antenna has two branches, which generate two resonant bands centered at around 888 and 1820 MHz. The achieved 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 results are presented and discussed; and good agreement is obtained between the simulated and measured results.
