antenna with double simultaneous operation or the original pentangle x and ku bands in the alternative for the prevention of road traffic

摘要

antenna for radar applications staff road safety, which is the choice of operation to be simultaneously or alternatively in both x and ku bands.based on sma female connector type jack with a single antenna. the invention relates to a novel symbolic rectangular substrate and patch in the pentacle.this is a device for receiving broadcast signals in ultra wideband uwb project using a connector having a top coaxialepermettant gaintwo bandwidth, small, good adaptability for x and ku frequency band with a low production cost.it consists of a single patch is connected to the outlet of a pentagram coaxial probe. the antenna is fed by a coaxial connector.the feed point is coupled to a connector sma (figure 7) inserted in the ground plane which subsequently increase the gain, directivity and bandwidth.the device according to the invention is particularly suitable for applications in radar control for speed limit violators in x and ku bands.
