gain in the case of 40 m thick BCB is smaller than in the case of 20 m BCB. This can be due to coupling power to the surface-wave modes, which increases as the thickness of the thin BCB film increases. ## CONCLUSION Brick-wall antennas fed by a coplanar waveguide and built in the MCM-D technology

β¦ Synopsis
w Ε½ .x layer where the dipole is located Fig. 5 a , then turns w Ε½ .x around the bend and moves to the next layer Fig. 5 b .
Comparing the maximum of the power inside the guide, we can see that the maximum of the power just before the bend is equal to the maximum of the power just after the bend.
IV. CONCLUSIONS
In conclusion, we have studied waveguides in three-dimen-Ε½ . sional layer-by-layer photonic bandgap PBG materials. A complete rod or part of two rods in neighboring layers have been removed for the creation of a straight waveguide or a waveguide bend. There is one particular frequency where a maximum transmission through a straight waveguide occurs. In that particular frequency and for certain configurations, a 100% transmission can be achieved along the waveguide bend.
