Design of Triple-Band Planar Antenna for LTE/WLAN Applications

In this study, low-profile triple-band planar dipole antenna is proposed for long term evolution and wireless local area network applications. A symmetric combination of rectangular, meander line and stub is etched on the metallic layer of a single sided printed circuit board to form the coplanar dipole antenna. The size parameters of the proposed antenna are changed to design and fabricate the antenna which can be operated at 1800/2400/2600/5100 MHz successfully. We use IE3D software to design antenna and choose the better parameters to manufacture the proposed antenna. The influences of dimension parameter of the proposed antenna on the resonant frequency and impedance bandwidth are described. The peak gains of the fabricated antenna are 3.03dBi, 2.92dBi, 4.8dBi and 2.03dBi at 1800MHz, 2400MHz, 2600MHz and 5100MHz, respectively. It can be used in LTE 1800/2600MHz and WLAN 2.4/5GHz frequency bands.
