Double slot array antenna design method and double slot array antenna designed thereby

Abstract

A method for designing a double slot array antenna and a double slot array antenna designed thereby are disclosed. The method for designing the double slot array antenna, includes the steps of: (a) setting the number of radiation elements of a double slot structure arranged in a waveguide of an array antenna to be designed, and setting a radiated power ratio required for each of the radiation elements; (b) modeling a simulation model for each of the radiation elements; (c) setting an offset distance of a main slot of each of the radiation elements applied to the simulation model; (d) deriving azimuth beam patterns for cases in which an offset distance and a length of a sub-slot of each of the radiation elements applied to the simulation model are changed; (e) selecting a similar azimuth beam pattern similar to a target azimuth beam pattern among the derived azimuth beam patterns; (f) calculating a radiated power ratio for the case corresponding to the similar azimuth beam pattern; and (g) comparing the calculated radiated power ratio with the set radiated power ratio to determine a design value of each of the radiation elements.
