Abstract

In this paper, we discuss how to control the side lobe level of corrugated metallic periodic leaky wave Antenna by its artificial surface impedances. Leaky Wave Antenna have beam steering ability by Frequency Scan or by artificial Surface Impedance control in the constant frequency. Side Lobe Level of Leaky Wave Antenna is Worse level of Antennas Side Lobe Levels and This level worst if other Modes of Leaky wave antennas is activated. Therefore just minimize the Side Lobe Level as well as. By applying the coefficients calculated by Taylor's method to the parameters of the leaky wave antenna (M and, accordingly, the depth of the teeth), the antenna was designed, simulated, built and evaluated and tested. The result of controlling the side lobelevel in this article is to reach the SLL of 18dB in the simulation, while in practice we reached the SLL of 16 dB in the measurement of the antenna made at 10 GHz frequency.
