Comments on “A Presentation of a Mathematical Formula to Design of a Quasi-Uniform Leaky-Wave Antenna With Ultralow Sidelobe Level”

An innovative method for designing a quasi-uniform leaky-wave antenna with transversely arranged periodic slots with varying length is presented in (Kiani et al., 2019). Although this design approach significantly reduces the sidelobe level, mathematical modeling errors appear to be present. These errors are corrected in this manuscript without compromising the generality of the method. Additionally, the accuracy of the modeling is determined by simulating an antenna with a single transverse slot and examining the relationship between its radiated power and the slot length. Finally, the validity of the simulation results in (Kiani et al., 2019) is critically evaluated.
