Abstract―A new built-in quad-band handset antenna for covering GSM900, DCS1800, PCS1900, and UMTS2000 bands is presented. Details of the antenna are discussed along with measured and simulated results. The simulation is based on the finite-difference time-domain (FDTD) method. Index Terms―Antennas, built-in antennas, multiband antennas, planar inverted-F antennas (PIFAs).

I. INTRODUCTION

T

HE sizes and weights of mobile handsets have rapidly been reduced due to the development of modern integrated circuit technology and the requirements of the users. Conventional monopole-like antennas have rem
