WIRELESS SENSING DEVICES INCLUDING STABLE NEAR-FIELD ANTENNA

Wireless sensing devices including stable near-field antennas are provided. A spacer layer is attached to a portion of the substrate adjacent to the antenna. The spacer layer has a thickness T, a relative permittivity k, and a figure of merit defined as the ratio of T (in micrometers) by k. The spac...

Zusammenfassung:Wireless sensing devices including stable near-field antennas are provided. A spacer layer is attached to a portion of the substrate adjacent to the antenna. The spacer layer has a thickness T, a relative permittivity k, and a figure of merit defined as the ratio of T (in micrometers) by k. The spacer layer has the figure of merit no less than 20 (micrometers). 本发明提供包括稳定近场天线的无线感测设备。隔层附接到与天线相邻的基板的一部分。隔层具有厚度T、相对电容率k、以及定义为T(以微米为单位)与k的比率的品质因数。隔层具有不小于20(微米)的品质因数。
