The paper describes the use of corrugated metal surfaces to reduce side and back antenna radiation. For example, this problem may arise if it is necessary to increase decoupling of the receiving and transmitting antennas in various radio systems and reduce positioning errors in navigation systems. Other ways of solving this problem include the use of a flat metal screen and various absorbing structures. This paper studies characteristics associated with the use of corrugated structure to reduce side and back radiation. The influence of parameters of corrugations and length of the structure is considered. The side and rear lobe level of radiation pattern is determined for weakly directional and a directional antenna. The efficiency of corrugated structure is compared with the flat screen. This paper describes two-dimensional problem in the E-plane. The problem was solved using method of integral equations in a two-dimensional formulation and using modeling in commercial CST Microwave Studio program. The article contains recommendations for choice of corrugated surface parameters, and can help to determine the achievable level of side and back radiation reduction. The bandwidth of corrugated structure has also been researched.
