Abstract: | Photonic band gap (PBG) crystals have been used as a perfectly reflecting substrate for many millimeter wave applications.
In this work the fin line directional coupler with substrate PBG was analyzed using the TTL - Transverse Transmission Line
- method. Compared to other full wave methods the TTL is an efficient tool to determine the coupler characteristics, making
possible a significant algebraic simplification of the equations involved in the process. In order to analyze this structure
the effective dielectric constant, the attenuation constant and the coupling were determined. The results obtained for this
application and the conclusions are presented.
