摘要

In this article, a TE_(20) mode substrate integrated waveguide (SIW) is utilized to designa leaky-wave antenna (LWA) which is capable to scan all the four directions (eightquadrants) simultaneously. With the eight radiated main beams, frequency beamscanning range of the proposed antenna is 56° in all the eight quadrants. By exploitingco-axial probe feeding and step impedance transformer, four ways microstrippower divider is designed which is further exploited to feed all the four TE_(20) modeSIW sections containing microstrip-coupled slotline-SIW transitions. For radiation,±45° rectangular slots are systematically placed on the top as well as bottom plane ofthe structure. The proposed antenna is working within the frequency range of 10-11.7 GHz having the maximum peak gain of 14 dBi. The proposed design is verifiedby experimental results which are in good agreement with the simulation. Along withthe utilization of higher order mode of SIW to achieve compactness and design simplicity,the four directional frequency beam scanning capability makes it a promisingcandidate in various microwave circuits and several beam-scanning applicationsincluding navigational and surveillance purpose.
