A linear directional smart antenna

The spacing between the present invention discloses a linear directional smart antenna, including a reflective plate and at least two sub-array of radiation by the radiation time around composed of the radiation sub-arrays arranged side by side on the reflector, the radiation sub-arrays adjacent between 1/4 wavelength and 1/2 wavelength. The present invention will be spacing between adjacent subarrays is reduced to radiation between 1/4 wavelength and 1/2 wavelength, while the radiation and the use of sub-arrays are arranged offset parallel feed to the premise of ensuring the quality parameters of the respective performance of the antenna effective reduces the lateral width of the linear directional smart antenna array, to achieve the miniaturization of the antenna, reduces wind resistance, but also to ease the psychological pressure misconceptions generated by nearby residents to some extent.
