This article describes a novel dual-polarized mm-wave antenna for mobile phone devices. The mm-wave antenna module consists of a 4-layer PCB, an extra metallic piece acting as a reflector, and four metallic pins. The four metallic pins are placed on the top layer of the PCB acting as an array of vertically polarized monopoles. On the bottom layer an array of horizontally polarized dipoles are fed using microstrip lines. The two middle layers act as ground. Simulations show very good performance in the 27 to 29.5GHz range. In this frequency range, the horizontally and vertically polarized arrays provide better than -1.5dB efficiency, and higher than 11.5dBi realized gain. Also, the reflection coefficient is mostly below -10dB in the 27 to 29.5GHz range for each individual antenna element. Beam-steering is possible up to ± 35° for both polarizations with a scan loss below 3dB.
