Chipless microwave identification tag

Summary

A chipless microwave identification tag (200) comprising: a dielectric substrate (210); and a plurality of antenna elements (220) made from a conductive material and disposed on at least one surface (205, 255) of the dielectric substrate (210); wherein when the tag (200) is excited by an incident microwave signal (131), a reflected wave (141) to identify the tag (200) is generated with a number of specific frequencies altered by microwave resonation of the antenna elements (220).
