Lower floor's radiant body and one of short circuit post connect the radio-frequency cable of upper strata radiant body.Upper strata radiant body can be to cover copper dielectric-slab
Or circular piece, lower floor's radiant body is between upper radiant body and antenna metal well floor；Levels antenna all forms omnidirectional's spoke
Emission mode, and cover different frequency range, realize difference in functionality, with each independent radio frequency output interface.Upper strata radiant body chi
It is very little less than lower floor's radiant body.It is loaded medium material or air between upper strata radiant body and lower floor's radiant body.Radio-frequency cable runs through
Short-circuit post be any one in four short-circuit posts.
Two-layer radiant body of the invention is covered each by two frequency ranges of height, and lower floor's radiant body works in low frequency band, uses
Connector direct feed, omnidirectional radiation is realized using discone antenna form, increases short circuit metal post and dielectric material designing load
Improve impedance matching property；Upper strata radiant body works in high-frequency band, is realized using microband paste form or monopolar form complete
To radiation, the defeated entry/exit of radio frequency is realized by the interior CA cable assembly of wearing in lower floor's radiant body and one of short circuit metal post.Change
Two-layer radiant body size, can adjust the working frequency range of aperture navigation antenna altogether；Change upper strata radiant body height and lateral dimension can
