This paper presents an approach to improve the efficiency of an array c12a microphone aperture by interleaving two different arrays in the same aperture area.Two sub-arrays working at different frequencies are interleaved in the same linear aperture area.The available aperture area is efficiently used.

The element positions of antenna array are optimized by using Invasive Weed Optimization (IWO) to reduce the peak side lobe level (PSLL) of the radiation pattern.To overcome fume mini flavors the shortness of traditional methods which can only fulfill the design of shared aperture antenna array working at the same frequency, this method can achieve the design of dual-band antenna array with wide working frequency range.Simulation results show that the proposed method is feasible and efficient in the synthesis of dual-band shared aperture antenna array.
