With.Wherein, the isolation between dual-mode antenna is a highly important index, if isolation is inadequate, can reduce radar effect away from
From will cause radar system when serious can not work.Isolation between cylindrical conformal antennas in the prior art will such as guarantee
Metal framework structure intensity, then can only achieve 50dB, be unable to satisfy requirement, and if improved by way of deepening fluting every
It, then can be to causing metal framework structure intensity to be substantially reduced, it is clear that also undesirable from degree.
Utility model content
In order to solve the above technical problems, the utility model provides isolation lift structure between a kind of cylindrical conformal antennas,
Isolation lift structure is in such a way that transmitting antenna and receiving antenna are laid out by high and low between the cylindrical conformal antennas, in addition inhaling
Isolation can be increased to 65dB by the setting of wave putty.
