Abstract

In this paper, the triple-band planar monopole antennas are designed for cellular communication, WiBro and WLAN(IEEE802.llb/g) communication and WLAN(IEEE802.lla) communication of 5GHz band. Various types of antennas are designed and examined experimentally as bended in the low and middle band radiation elements to decrease antennas size and increased radiation elements width to improve bandwidth. The proposed antennas are improved by 11% in antenna size with bended low-band radiation elements down and are extended by 30%$\sim$40% in bandwidth by increasing the width of the radiation element at 800MHz band.
