Abstract

The invention provides a convex optimization-based near-field array antenna pattern synthesis method. The method comprises the following steps of: 1, determining a shape of a main lobe, a position range in which minor lobe control needs to be carried out, and a peak minor lobe level; 2, establishing a radiation model of a radiation near-field region on the basis of a point focusing antenna array;and 3, establishing a convex optimization model and solving motivation of the antenna array. The method has the advantages of generating radiation near-field regions into patterns with any shape and controllable minor lobes and being high in calculation speed, and can be used for optimum design of near-field planar array antennas.

Description

technical field [0001] The invention belongs to the technical field of antennas, in particular to a method for synthesizing pattern patterns of near-field array antennas based on convex optimization. Background technique [0002] Unlike antennas that generally work in the radiation far-field area, for some specific occasions, the energy radiated by the antenna is required to be concentrated on a specific point or area in its near-field area, which requires a near-field focusing antenna. Research on near-field antennas has been going on for a long time. Near-field focusing antennas with high energy density in a specific area can not only be used to improve the detection and imaging capabilities of medical and industrial inspection systems, but also can be used in access control systems, microwave wireless energy transmission systems, radio frequency identification systems, and microwave radio systems. , has broad application prospects and research value. [0003] Compared w...
