Design of Dual-band Coplanar Dipole Antenna for LTE Applications

Abstract

In this paper, we propose a simple structure of coplanar dipole antenna with a tuning stub. The antenna which exhibits dual band is designed and fabricated respectively. The influences of stub length parameter of coplanar dipole antennas on the resonant frequency, return loss and bandwidth are also discussed. We use IE3D software to design coplanar dipole antennas and choose the better stub length parameter to manufacture coplanar dipole antenna. The proposed antenna here with the size of 150mm×30mm×1.6mm possesses the dual-band characteristics, 692MHz-832MHz and 1451MHz-1926MHz. The fabricated antenna is suitable for long term evolution (LTE) applications at 700MHz and 1800MHz.
