In this letter, a new quasi-uniform leaky-wave antenna is proposed. The structure of antenna is based on an air-filled rectangular waveguide in which the radiation occurs through transverse slots on the broad wall of the waveguide. This antenna is designed using a systematic method based on the thinned array theory in order to achieve a low side-lobe level (SLL). The designed antenna radiates at center frequency of 10 GHz at
