Multiband mobile phone antenna for GNSS application

In this article we have presented a new design of a monopole antenna mobile phone, which covers several bands with circular polarization. The proposed antenna generates five resonant frequencies. Our antenna has a bandwidth band that has bands of wireless communication systems such as GSM (880 960 MHz), DCS (1710 1880 MHz), PCS (1850 1990 MHz), UMTS (1920 2170 MHz), WiBro (2300 2390 MHz) and ISM (2400 2483 MHz) and GNSS, including COMPASS (1559.052 1591.788 MHz), GPS (1575.42 5MHz), GLONASS (1602 1615.5 MHz), Galileo (1189 1214 MHz). We discussed the various parameters of the antenna, such as return loss, radiation pattern and axial ratio AR.
