Formulation of the problem. In the microwave range, the implementation of radar systems for spatial surveillance, remote sensing and information transmission systems requires relatively simple and reliable low-profile antennas that have a narrow radiation pattern in one of the planes and a high gain.

Purpose. Demonstrate the feasibility and efficiency of implementing a high-gain linear antenna based on a periodic leaky wave antenna with series feeding of an integrated aperture.

Results. The possibility of effective implementation of an antenna system with a high gain based on a linear periodic leaky wave antenna in the range of 9.2-9.5 GHz is shown. The radiating aperture of the antenna contains a flat dielectric waveguide integrated with a metal periodic grating with rectangular grooves. The values of the geometric parameters of the emitting aperture are indicated. The results of mathematical modeling using an original 2D computational algorithm and full-wave 3D electromagnetic modeling are presented, confirming the effectiveness of the antenna design with the stated geometric parameters.

Practical significance. The developed integrated periodic leaky wave antenna of the microwave range can be used to increase the azimuth resolution and range of radar systems, increase the energy potential of information transmission systems without increasing the transmitter power.
