研究目的
To design a substrate integrated waveguide (SIW) slot antenna with dual wide beamwidths for future 5G applications, achieving wide beamwidths in both E- and H-planes at dual frequency bands with a low profile.
研究成果
The proposed SIW slot antenna achieves dual 5G sub-6 GHz frequency bands with wide beamwidths in both radiating planes and a low profile of 0.12λc. It is suitable for base-stations and phased arrays in future 5G mobile communications.
研究不足
The study focuses on simulation results; practical implementation and real-world performance may vary. The antenna's performance in different environments and its integration into 5G systems are areas for further investigation.
1：Experimental Design and Method Selection:
The antenna design includes a differentially-driven feeding structure, a SIW cavity, and an octagon patch with two orthogonal radiating slots. The design aims to achieve dual frequency bands and wide beamwidths for 5G communications.
2：Sample Selection and Data Sources:
The antenna is fabricated using inexpensive F-4B substrates with specific dielectric properties.
3：List of Experimental Equipment and Materials:
F-4B substrates (ε=2.2, tanδ=0.007), microstrip lines, feeding probes, and metalized vias.
4：2, tanδ=007), microstrip lines, feeding probes, and metalized vias.
Experimental Procedures and Operational Workflow:
4. Experimental Procedures and Operational Workflow: The antenna is excited by off-centered microstrip lines, with resonances adjusted by the arrangement of feeding lines. The design is simulated using Ansys HFSS.
5：Data Analysis Methods:
Simulated S-parameters, gain, isolation, and radiation patterns are analyzed to evaluate antenna performance.
