本文介绍了在介电常数ε_γ=2.1、厚度h=1.6mm的聚四氟乙稀(PTFE)基底上的宽带微带天线的实验研究。就同轴馈电的圆盘形天线来说,通过修改基底上的馈电,能获得17％的带宽改善。在成圆形的被修改过的贴片上所完成的试验表明:比一般的微带贴片有80％的进一步带宽改善。
This paper presents an experimental study of a broadband microstrip antenna on a polytetrafluoroethylene (PTFE) substrate with a dielectric constant of ε_γ = 2.1 and a thickness of h = 1.6 mm. For coaxial fed disk antennas, a 17% improvement in bandwidth can be achieved by modifying the feed on the substrate. Experiments done on a circular modified patch show that there is an 80% further bandwidth improvement over a typical microstrip patch.
