Abstract
In order to enhance the multi-object detecting and tracking capability,a four-beam millimeter wave frequency scanning leaky wave antenna (LWA) based on spoof surface plasmon polaritons (SSPP) has been proposed. According to the theory of sinusoidally modulated reactance superposing surface (SMRSS),Quad-beam LWA is realized by etching periodical slots on the top surface of substrate integrated waveguide (SIW),and uniform slots etched on the bottom layer is used to eliminate the open-stopband effect. The measurement shows that the four beams can scan from -52° to 22° within the frequency band from 29 GHz to 30. 2 GHz,achieving a total of 74° scanning range,and the beam scanning is up to 18°/%BW,which not only saves the spectrum source but improvs the multi-target detection efficiency.
