Abstract. The propagation and radiation characteristics of forward and backward leaky waves in 2D-periodic printed-circuit arrays on substrate-integrated waveguides with meander-shaped slots are numerically investigated. For finite-size arrays, the matching and radiation characteristics are computed depending on frequency and progressive phase shift between waveguides assuming uniform excitation of all array inputs. Studies show that the achieved scanning sector in the frequency range from 9 to 13 GHz is around 90° in the elevation and 40° -72° in azimuth with the phase shift of 75°. It is also shown that at a given frequency and with a change in the phase shift the array beam scans along the surface of an almost circular cone with the angle at its vertex depending on the frequency. This angle varies with frequency change, which ensures the 2D scanning capability of the array. A comparison with the earlier published results is given.

Keywords: leaky-wave antenna, 2D-periodic waveguide slotted array, substrate-integrated waveguide, forward and backward leaky waves, frequency-phase scanning.
