摘要：
A dual beam leaky wave antenna (LWA) array is designed and investigated in this paper, which using the substrate integrated waveguide (SIW) technology based on TE20 mode at X-band. The dumbbell-shaped slots are etched out on the both sides of SIW. Using these types of slots has increased the bandwidth of the antenna, so that the proposed antenna bandwidth is between 9.4-14 GHz. Another advantages of this structure are the good gain, proper directivity, and radiation efficiency, so that at 12 GHz the antenna peak gain reaches to 12.6 dB. The beam scanning range changes from 5 degrees to 78 degrees in the first and fourth quadrants. The scanning range of this antenna is similar to about 73 degrees degrees in each quadrant that makes it proper for radar applications. This antenna is analyzed and simulated by the CST Microwave Studio software.
