Abstract: (2007 Views)
In this paper, a novel waveguide array antenna composed of non-inclined slots in the narrow wall of the waveguide, which are excited with rectangular Iris is introduced. This new method in addition to improving impedance and radiation characteristics has an easy production process. Also, because of using non-inclined slots, the antenna has very low cross polarization level. In this paper, in the first step, suitable radiating elements for designing a linear slot array antenna were considered, and then a linear array suitable surveillance radar with 136 elements with Taylor distribution is designed and simulated with HFSS at the frequency of (2.7 - 3.1) GHz. Finally, the antenna has been fabricated and tested. The results of the test and simulation are in good agreement.
