Abstract :
The effect of one, two and three lines of EBG mushroom-like cells on the coupling of two different 2-element arrays was analyzed and described. It was demonstrated that a certain surface waves attenuation is already achievable with just one row of cells, even though a better performance is obtained when more lines are added. A bandgap investigation technique based on the analysis of the transmission coefficient of a two-patch antenna array separated by one, two and three lines of EBG cells was used throughout the paper. e analyze two types of antennas (monopole and square patch) both resonating at 15 GHz but with different radiation mechanisms in order to isolate the contribution of the EBG and better understand its effect on different polarized surface waves.
