Abstract

The invention belongs to the technical field of an omnidirectional circular polarized antenna and discloses a microminiature low profile omnidirectional circular polarized antenna. The antenna comprises a radiation portion, wherein the radiation portion comprises an upper medium board, four coupling plates, a circular metal ring, a circular metal disc and a center metal column, and the coupling plates, the circular metal ring and the circular metal disc are printed on an upper surface of the upper medium board. The antenna is advantaged in that four metal short circuit columns are connected between tail ends of the coupling plates and a metal floor, a current spreading path on the coupling plates is extended, the transverse dimension of the antenna is effectively reduced, and profile height is further reduced; the inner coupling plates are added in the outer coupling plates, coupling energy among antenna units is enhanced, compared with the prior art, on the condition that directional diagram performance is guaranteed, the dimension of the antenna is substantially reduced, the coupling energy among the control units can be excellently controlled through adjusting distances between the inner coupling plates and the outer coupling plates and length of the inner coupling plates, and thereby antenna work frequency is adjusted.

Description

technical field [0001] The invention belongs to the technical field of omnidirectional circularly polarized antennas, in particular to an ultra-small and low profile omnidirectional circularly polarized antenna. Background technique [0002] Omnidirectional circularly polarized antennas not only have the advantages of anti-jamming and suppressing multipath effects, but also have the characteristics of omnidirectional radiation. Therefore, omnidirectional circularly polarized antennas are widely used in remote sensing and telemetry, space vehicles, and maritime communications. And wireless communication and other fields have a wide range of applications. At present, a lot of research has been done on the omnidirectional circularly polarized antenna at home and abroad. An omnidirectional circularly polarized antenna is a type of omnidirectional antenna. The so-called omnidirectional antenna means that the horizontal pattern shows uniform radiation for 360°, that is, it has n...
