研究目的
To propose a high-isolation dual-polarized quad-patch antenna fed by stacked substrate integrated waveguide (SIW) suitable for millimeter-wave band, focusing on enhancing channel capacity through polarization diversity for future 5G applications.
研究成果
The proposed high-isolation dual-polarized quad-patch antenna achieves good radiation performance at 38 GHz, suitable for future 5G applications. The design demonstrates high isolation between ports and low cross-polarization levels, with potential for further optimization.
研究不足
The |S11| of the elements needs further adjustment to improve the array's performance. The measurement above 40 GHz is not available due to the frequency limitation of the network analyzer.
