Abstract :
A substrate integrated waveguide (SIW) leaky wave antenna with transverse slots has been presented. This SIW leaky-wave antenna has beam scanning from near broadside to forward endfire. However, the nature of the waves propagating in the SIW with transverse slots was not analyzed theoretically. Usually, the SIW can be approximated as a rectangular waveguide. Therefore, for understanding the modes propagating on an SIW with transverse slots, the transverse slotted rectangular waveguide is used. The metal and dielectric are assumed lossless in this investigation.
