Analysis and Design of an Antenna Array with a Cosecant Radiation Pattern Based on the SIW Structure

New modern radar systems are still being researched, developed and improved. Today, radar systems are subject to stringent design requirements. This paper deals with analysis and design of an antenna array with a cosecant pattern based on the SIW structure for a FMCW radar system, which uses digital beamforming. The first part of this paper is focused on the basic concepts of antenna systems. Next, the synthesis and design of an antenna array is described. Finally, the results of the simulation feeding network based on the SIW structure are presented along with verification of these results.
