TL;DR: In this paper, a 5-element planar dipole array antenna is designed for operation at 1.9 GHz band for basic station applications with S 11 < −14 dB, which is easily constructed by printing on both sides of a dielectric (FR4) substrate.
Abstract: A 5-element planar dipole array antenna is analyzed and successfully implemented. The proposed antenna is designed for operation at 1.9 GHz band for basic station applications with S 11 < −14 dB. The planar dipole array antenna comprises of a 1×5 dipole array and fed by a microstrip line. This structure is easily constructed by printing on both sides of a dielectric (FR4) substrate. The measured −14 dB return loss (VSWR 1.5:1) impedance bandwidth is around 7.0% (1.79–1.92 GHz). A reflector is put behind the dipole array to obtain directional radiation and high gain, and the measured maximum gain for operating frequencies across the 1.9 GHz band is about 6.9–8.6 dBi. The measured results of radiation efficiency, radiation pattern, antenna gain and return loss show that this dipole array is with a good performance.

TL;DR: A new design of planar dipole array antenna (PDAA) is presented, which can be used in WLAN frequency band and can be operated at 5.2/5.8 GHz successfully.
Abstract: This paper presents a new design of planar dipole array antenna (PDAA). Radiated patches are etched on the metallic layer of a double-sided printed circuit board (FR4) to form the PDAA. The two symmetric flags with trapezoid patch are designed on both side of the print circuit board to form the basic dipole element. IE3D software is used to design PDAA. Better parameters are selected to manufacture the proposed array antenna. The fabricated 4×8-element planar dipole array antenna can be operated at 5.2/5.8 GHz successfully. With suitable size parameters of the dipole element, PDAA is fabricated. From the measured results, the wide bandwidth about 1.97GHz is obtained. The peak gain of the fabricated PDAA with reflector is 15.55dBi at 5.2GHz and 17.53dBi at 5.8GHz. This high gain planar dipole array antenna can be used in WLAN frequency band.
