提出了一种用于2.45 GHz和5.8 GHz有源射频识别(RFID)标签的双频共面波导馈电透明天线。以镀银聚酯为导电层，以聚对苯二甲酸乙二酯为衬底的AgHT-8薄膜被用于设计和制造具有80%以上的高透明度的天线，这足以提供对标签器件表面进行层叠的能力，而检测机会很小。拟议设计的总尺寸为36 39 0.175 mm(3)。在低频段和高频段分别获得了59.34%(1.6~2.95 GHz)和16.95%(5.4~6.4 GHz)的测量带宽。与非透明设计相比，该天线具有更小的厚度和更轻的结构。
A dual-band coplanar-waveguide (CPW)-fed transparent antenna for active radio-frequency identification (RFID) tags working at 2.45 GHz and 5.8 GHz is proposed. AgHT-8 thin film, includes the silver-coated polyester as the conductive layer, and polyethylene terephthalate as the substrate, is used to design and fabricate the antenna with high transparency of above 80%, which is sufficient to provide the ability to laminate the surface of the tag devices with little chance of detection. The overall dimension size of the proposed design is 36 39 0.175 mm(3). The measured bandwidth of 59.34% (1.6 to 2.95 GHz) and 16.95% (5.4 to 6.4 GHz) is achieved for the lower band and the upper band, respectively. The proposed antenna has considerably less thickness and a lighter structure compared with the nontransparent designs.
