In this paper, a new design of pencil-beam planar dipole array antenna (PDAA) with reflector back has been designed and fabricated for IEEE 802.11ac outdoor applications. The proposed antenna is a planar array combined with a reflector. The planar array is comprised of 4 x 4 x 3 single elements which are placed on an FR4-epoxy substrate with the size of 241 mm x 194 mm x 1.6 mm. This design has very good simulation results in terms of the radiation pattern, gain and input impedance bandwidth. A very high gain of 18.2 dBi has been achieved at 5.5 GHz, and the bandwidth is relatively wide with about 23% of the center frequency, which covers the whole bandwidth allocated for the application. A prototype has been fabricated and measured. The measurement results have very good agreements with the simulated data.
