Pattern Synthesis Method for a Center Holed Waveguide Slot Array Applied to Composite Guidance
The circular waveguide slot array with a hole in the center b one of the key techniques to realize the shared aperture composite guiding.Due to the influence of the hole, a sound realization of low side-lobe pattern is the difficulty and key for this antenna.The waveguide brandside shunt slot array only can realize low side-lobe by controlling the distribution of the amplitude.And it needs to control the slot offsets to achieve the distribution of amplitude.But it is already difficult to realize low side-lobe for this configuration, and the influence of the slot offset will not be ignored.So in the paper, we propose a new pattern synthesis method, which combine genetic algorithm and Elliotts design method for slot array.And this method takes slot offsets and mutual coupling into account, then adjust the slotsparmeter to achieve low side-lobe.The combination of the designation of array parameter and pattern synthetic not only realize the low side-lobe pattern synthesis, also achieves the designation of the array parameters at the same time.
