Abstract. A phased array antenna with one-dimensional phase scanning, containing two flat arrays of a hollow rectangular leaky-wave waveguide with a translucent narrow wall, was proposed and investigated. The translucent wall is made in the form of a lattice of cylindrical conductors. Flat arrays are angled to each other and, at the interface, are excited by a linear phased array of rectangular waveguides. To realize an in-phase front with a uniform amplitude distribution, the lattice period of cylindrical conductors increases, and the size of the wide wall of the leaky-wave waveguide decreases in the direction of its propagation according to the found law. Using numerical simulation based on the finite element method, the dependences of the gain of the antenna array on the frequency and scan angle are investigated. The maximum value of the antenna array efficiency is more than 0.9, the frequency band at the 0.7 efficiency level is more than 5%. The maximum value of the antenna array efficiency is more about 0.9, the frequency band at the 0.7 efficiency level is more than 5%. Scanning sector by the level of the gain dropping - 3 dB is more 50 degrees.

Keywords: phased array antenna, leaky-wave waveguide, numerical simulation.
