Abstract
A slotted cylinder antenna with the original matching device is presented in the paper. A slotted cylinder antenna is made on the shape of longitudinal slot based on a metallic tube with diameter much smaller than the wave length. The length of the slot is much smaller than the wave length in free space. The antenna parameters are found by numerical method in the strict electrodynamic formulation of the problem. For this purpose the construction of the matching device is taken into account in the electrodynamic model of the antenna. Reached theoretical results in antenna bandwidth of examined antenna demonstrate good quantitative match with experimental results. The method and original matching device suggested in the paper are characterized by simplicity of the antenna matching with a feeder.
