Abstract
In this paper, spiral meander monopole printed antenna for dual band operation in GPS(1.57~1.577 GHz) and WiBro(2.3~2.4 GHz), WLAN(2.4~2.48 GHz) is proposed. Spiral(positive coupling) mounted end of monopole(small current) and meander mounted fed of monopole(big current) for reduce frequency ratio. Bandwidth(-10 dB) of the antenna is measured 130 MHz(1.49~1.62 GHz) in basic resonance frequency and 330 MHz(2.29~2.62 GHz) in harmonic resonance frequency($3{\lambda}_H/4$). The peak antenna gains are measured 2.86 dBi in GPS(1.57 GHz), and 3.49 dBi in WiBro(2.35 GHz), and 3.71 dBi in WLAN(2.44 GHz).
