This paper presents the application of a substrate integrated waveguide (SIW) for the design of a leaky wave antenna radiating from a slot in the broad wall. The antenna radiates into a beam split into two main lobes and its gain is about 7 dB at 19 GHz. The characteristics and radiation aspects of the antenna are discussed here. The measured antenna characteristics are in good agreement with those predicted by the simulation. Due to the SIW technology, the antenna is suitable for integration into T/X circuits and antenna arrays.

We present the investigation of symmetry influence in substrate integrated waveguide (SIW) band-pass filters using symmetrical posts for the suppression of TEi0 modes, with i = 2,4, . . .. This is of particular importance for SIW band-pass filters with a wide bandwidth. We show theoretical and experimental results for a particular filter with a bandwidth of more than 28% demonstrating an improvement in the suppression of spurious transmission by 19 dB.
