Abstract :
In this paper, a wide-band phased array antennas with unequal space presented, antenna consists 18 ridge horn radiating elements. which the array elements arranged by the unequal space, so that the performance that the patterns in the visible range has a peak value in the radiation direction and do not have grating lobes in wide band. The design of phased array antenna for a wide-band application is discussed. The rule of arrays with unequal space for several elements is derived using this synthetical method. Sinulation results show that the array antennas can scan in a range of ±45°in wide band.
