Research on side-lobe radiation characteristic of printed dipole array

In the paper, the radiation characteristic of printed dipole array along side-lobe direction is researched. The electric field intensity values in side-lobe area are calculated using FEKO under different situation. It is also analyzed how metal plate and scanning angle influence electric field intensity values in side-lobe region. Besides, through the peak values and valley values of electric field intensity along side-lobe direction, the possibility of using peak value and valley value identify the number of side lobe is discussed.
