Problems solved by technology

However, the theoretical analysis and engineering design of the conformal array will be more complicated, because the positions of the units are not on the same plane, and the distance between the units is not all equal, so that the pattern of each radiation unit is complex;

Abstract

The invention provides an ultra-wideband microstrip cylindrical conformal array antenna, which is composed of a plurality of microstrip logarithmic periodic antenna elements and a hollow cylinder which are conformal. The microstrip logarithmic periodic antenna element consists of two identical fractal dipole array patches attached to the inner and outer surfaces of the cylindrical carrier respectively and symmetrically distributed with respect to the rectangular feeder. Each fractal dipole array patch consists of 9 fractal monopoles with a Koch curve structure and rectangular feeders. A coaxial feed line feeds simultaneously a plurality of microstrip logarithmic periodic antenna elements, and energy is radiated from one end of the shortest dipole. The invention has the advantages of easy conformation, small size, ultra-wide band, high gain, simple structure and the like, and is suitable for communication, lateral direction, reconnaissance, electronic countermeasure and the like.

Description

technical field [0001] The invention relates to the technical field of ultra-wideband antennas, in particular to an ultra-wideband microstrip cylindrical conformal array antenna. Background technique [0002] In recent years, ultra-wideband antennas have been widely used in military applications such as electronic countermeasures systems, ultra-wideband radars, satellite communications, and mine detection, and there are also extensive demands in high-speed wireless local area networks, home networks, and wireless phones. Although microstrip-based ultra-wideband antennas have the advantages of low profile and easy conformality, their application range is greatly limited due to the inherent defect of microstrip antennas with narrow frequency bands. [0003] The ultra-wideband cylindrical conformal array antenna is an antenna form in which multiple conformal array antennas are located on the inner and outer surfaces of a hollow cylindrical carrier. Through the reasonable design...
