FIELD: antenna engineering, can be used as a receiving and transmitting conform antenna. SUBSTANCE: antenna has a metal body in the form of an inverted truncated cone with a flange for antenna attachment, closed with a dielectric cover lying on the flange. Two plates are available inside the body. The upper (metal) of the antenna body in this section, arranged without any gap under the dielectric cover, is made in the form of a disk with four protruding open-ended stubs and with four stubs connected to it on the lower side and closed to the antenna body. Similar stubs are spaced at an angle of 90 deg. relative to one another, and each group of similar stubs is shifted relative to each other through 45 deg. The lower (dielectric) plate with a one-sided metallization, oriented upwards, is made in the form of ortahedron, whose maximum size is less than the diameter of the upper plate with four stubs positioned under the short-circuited stubs of the upper plate and electrically coupled to them. Electrically coupled to the geometric center of metallization of the lower plate is the supply line, which is the extension of the central conductor of the radio-frequency connector located outside the antenna body in the center of its base. The dielectric cover, both plates and antenna body make up a system of two coupled resonators that can expand the service band up to 25 to 27%. EFFECT: expanded service band. |
