The proposed antenna covers a frequency range from 2 to 12 GHz with an average gain of 12.5 dBi which has improved by a lens structure. In the first step, the design proceeding of the antenna has been discussed, and then, some of the unique futures of the proposed antenna which promoted it to use in quantum attack systems, such as linear momentum, a good Envelope Correlation Coefficient, and Gaussian pulse response, are discussed.engrestrictedAccessarticle311200068296550000110.1002/mmce.22872Quantum key distributionRF fingerprintVivaldi antenna2-s2.0-85112644125
