Equal-hexahedron conformal broad-band phase-stabilizing dual circularly-polarized antenna

Abstract

The invention provides an equal-hexahedron conformal broad-band phase-stabilizing dual circularly-polarized antenna, and aims to provide the equal-hexahedron conformal broad-band phase-stabilizing dual circularly-polarized antenna that is simple and reliable without adopting an over complex structure. The equal-hexahedron conformal broad-band phase-stabilizing dual circularly-polarized antenna is realized by the following technical scheme: an equal-hexahedron hexagonal incenter is surrounded by zigzag-form monopoles together; the zigzag-form monopoles are uniformly arranged at the equal angle of circumference of 60 degrees by adopting the same metal grounding plate; and the equal-hexahedron conformal broad-band phase-stabilizing dual circularly-polarized antenna is formed through input ports for feeding six conformal monopole antennas respectively. According to the equal-hexahedron conformal broad-band phase-stabilizing dual circularly-polarized antenna, the broad band, phase stabilization and left and right rotating circular polarization of the antenna are realized without increasing an extra complex structure; and therefore, the problems of large size, complex manufacturing process and the problem that only one polarization mode can be realized in the prior art are solved.

Description

technical field [0001] The invention relates to an equihexahedral conformal broadband phase-stable double circular polarization antenna mainly applied to differential GPS. technical background [0002] The appearance of modern communication equipment has become much lighter with the development of integrated circuits and other technologies, while antennas, especially some large-scale antenna systems, are often relatively bulky, which affects the flexibility of antenna applications, limits its scope of use, and hinders It has promoted the development of miniaturization and integration of radio equipment. The polarization of the polarization bandwidth antenna refers to the orientation of the electric field vector of the antenna in the direction of maximum radiation. When the orientation of the electric field vector is constant, the antenna is a linearly polarized antenna: when the orientation of the electric field vector changes with time, and its vector endpoints form an ell...

Problems solved by technology

There are many types of antennas with broadband circular polarization performance, such as stacked microstrip circularly polarized antennas. This type of circularly polarized antenna has better performance in terms of impedance bandwidth, axial ratio, gain, and beam width. Complex double-fed and four-fed networks, the stability of the phase center is still very large; Archimedes spiral antenna, that is, planar Archimedes spiral antenna and hemispherical Archimedes spiral antenna, Archimedes spiral antenna As a form of planar helical antenna, there are generally several kinds of single-arm, double-arm and four-arm in structure. For the double-arm or four-arm helical antenna, because the antenna is symmetrical in structure, the advantages are frequency bandwidth, The phase center is stable, the disadvantage is that the size is large, the manufacturing process is complicated, and only one polarization mode can be realized
