By using low-permittivity substrates, both the attenuation and the bandwidth can be improved. An ultra-broad bandwidth up to 77 GHz could be obtained with the BCB polymer as substrate in thin film on low-resistivity silicon wafers.}, title = {Ultra-broad bandwidth and low-loss GCPW-MS transitions on low-k substrates}, journal = {Electronics Letters}, issue = {13}, volume = {46}, year = {2010}, month = {June}, pages = {931-933(2)}, publisher ={Institution of Engineering and Technology}, copyright = {© The Institution of Engineering and Technology}, url = {https://digital-library.theiet.org/;jsessionid=1pocfqn775ge7.x-iet-live-01content/journals/10.1049/el.2010.0986} }
