Design of printed dipole array with reflector

In this paper, we propose a technique to reduce the back side radiation in antenna array. This technique allows very simple way for feeding network of the array by using a reflector in each element array like it is done with Yagi antenna. This new structure permits to avoid metallic reflector in back side of the array and then it reduces the size of the antenna [1 to 6] with good performances. In the first part of the paper, we present antenna without and with reflectors. In the second part, we present a four element antenna with a non uniform distribution and a director in each antenna element in order to increase the gain performances and the side lobe level. All arrays are optimized by using HFSS An soft software.
