In this article, a comb-line array (CLA) antenna with shaped patterns is proposed for millimeter-wave traffic monitoring radars in intelligent transportation systems (ITS). It is demonstrated that ...

The width of the pattern is decreased with increasing the ratio of the antenna length to the radiated wave length L/λ and is 17° for L/λ=10 and 12° for L/λ=20. Thus, the plasma antenna operating in ...

Figure 4 shows the radiation patterns of the travelling-wave bowtie antenna with a meander series of five and seven excitations at their center frequencies. The patterns are roughly the same, ...
