Investigation of hybrid Hexagonal antenna arrays for Smart antenna Applications

In this paper, presented two novel types of antenna arrays constructed from combination of linear and hexagonal antenna arrays for smart antenna applications. These types are concentric hexagonal and hexagonal cylindrical antenna arrays. Antenna elements are uniformly distributed and excitation amplitude coefficients are computed using firefly algorithm. The two antenna array configurations are compared in the context of beam forming capability, side lobe level and half power beam width and their values are tabulated. Simulation has performed by using MATLAB software.
