Abstract
A method for designing a double slot array antenna is disclosed, aiming to achieve a beam pattern similar to a target azimuth pattern and low side lobe levels. The method involves seven steps: (a) Setting the number of radiation elements and the required radiated power ratio; (b) modeling a unit cell simulation model; (c) setting the main slot offset distance; (d) deriving azimuth beam patterns for various cases by changing the sub-slot offset and length; (e) selecting a similar azimuth beam pattern by comparing patterns to a target pattern; (f) calculating the radiated power ratio for the selected case; and (g) finally, comparing the calculated power ratio with the set ratio to determine the final design value of each element.
