使用聚酯织物作为天线馈线的基材制造了柔性纺织天线,并在弯曲情况下进行了研究。该天线是由导电织物制成的背腔缝隙天线(CBSA)。馈线的基材也是纺织片材而不是传统材料,以使天线更加灵活。此外,馈线通过直接缝制固定在CBSA上,以防止馈线和天线之间出现间隙。根据天线的曲率半径测量了 2.4 GHz 频段的天线性能,并与之前研究中用胶带固定馈线的天线性能进行了比较。结果表明,缝纫情况下的 -10 dB 带宽比之前的情况更宽。因此,我们建议通过减少馈线和天线不必要的变形来改善天线特性。
A flexible textile antenna has been fabricated using a polyester fabric as a substrate of the feed line to the antenna and studied in bending cases. The antenna is a cavity-backed slot antenna (CBSA) made of conductive textiles. The substrate of the feed line is also a textile sheet rather than conventional material in order to make the antenna more flexible. Moreover, the feed line is fixed by sewing directly to the CBSA to prevent a gap between the feed line and the antenna. The antenna performances in 2.4-GHz band have been measured depending on the radius of curvature of the antenna and compared with those fixing the feed line by adhesive tape in the previous study. The results revealed that the -10 dB bandwidth in the sewing case is wider than that by the previous case. Thus, we suggest that the antenna characteristics can be improved by the reduction of unnecessary deformation of the feed line and the antenna.
