A 30 bit high‐density circular chipless RF identification tag based on C‐shaped open end polarisation independent slots is presented. The encoding capacity of this design is enhanced in a compact size. Patch diameter of the tag is 24 mm. Circularly polarised incident plane waves are used for excitation. Data capacity of 30 bits is achieved in the frequency band of 3.1–11.7 GHz. Spectral signature‐based radar cross‐section results are also measured for flexible and temperature sensor integrated design. The prototype is inkjet printed on Kapton ® HN heat resistant conformal sheet.
