Design of new planar waveguide-slot array antennas with a centre hole using genetic algorithm

The design method of new planar waveguide-slot array antenna with a centre hole is presented in the paper. Throughout analyzing the effects on patterns sidelobes in the waveguide-slot array antenna with a centre hole, the array's patterns is optimized by Genetic Algorithm method. The results of design are good and compare very well with ones analyzed by the emulational software of the electromagnetic fields. The array antennas are widely applied in the fields of the complex detectors especially ones with radio and optics on aircraft.
