Title:  Millimeter-Wave Dual-Polarized Frame-Integrated Patch Antenna Array for 5G Mobile Handsets

Abstract:
A dual-polarized frame-integrated four-element patch antenna array is presented for 5G millimeter-wave (mmwave) mobile handsets applications. Two types of dualpolarized excitation schemes, namely exciting vertical/horizontal polarizations or ±45° polarizations, are evaluated and compared. The latter has better stability of the resonant frequency and higher port isolation. The proposed ±45° polarized array is then integrated with the metal frame and fed with a set of 2×4 feedlines. Metallic fences are used to further improve the resonance performance and decrease the crosspolarization level (XPL). The proposed design can cover a -10 dB impedance bandwidth of 7.9%, with the port isolation above 14 dB and 3 dB beam steering range of 108°.
