Abstract :
A dual-beam substrate integrated waveguide (SIW) periodic leaky wave antenna (LWA) is designed and fabricated. The dual-beam operation is obtained by using leakage from the side walls of the SIW. The two beams are mirror image of each other. The feeding arrangement is simple and the antenna as a whole is easy to fabricate. A backward end fire to forward end fire scanning range of almost 74° is obtained by varying frequency from 8.5GHz to 13.3GHz. Side lobe level is better than 13dB in the specified frequency range. Measurement results match well with simulated results.
