N2 - In this paper, an 8 × 1 dual-polarized linear array antenna is proposed for a random line-of-sight over-the-air measurement system. The proposed array antenna operates over the frequency band of 1.6-2.7 GHz. A self-grounded bowtie is optimized as the array element. A compact wideband two-port feeding network is designed and manufactured to differentially excite each element, while each port excites one of the two orthogonal polarizations. Corrugated plates have been employed in the transverse plane of the linear array in order to achieve the same beamwidth for both polarizations over the entire band. A prototype has been manufactured and the measured reflection coefficient is better than -10 dB. The realized gain and the half-power beamwidth of the array in the transverse plane of the array remain fairly constant over the entire band of interest.
