摘要

A high-isolation dual-polarized quad-patch antenna fed by stacked substrate integratedwaveguide (SIW) that is suitable for millimeter-wave band is proposed inthis paper. The antenna consists of a quad-patch radiator, a two-layer SIW feedingstructure and two feeding ports for horizontal and vertical polarization. The twolayerstacked SIW feeding structure achieves the high isolation between the twofeeding ports (|S_(21)| ≤ −45 dB). Based on the proposed element, a 1 × 4 antennaarray with a simple series-fed network is also designed and investigated. A prototypeworking at the frequency band from 38 to 40 GHz is fabricated and tested.The results indicate that the proposed antenna has good radiation performance at38 GHz that covers future 5G applications.
