In this article, a high-performance T-junction has been fabricated based on the nonradiative dielectric waveguide, which achieved well-balanced outputs in excess of -4 dB over a frequency range of 2 GHz at a center frequency of 35 GHz.Abstract:
A high-performance T-junction has been fabricated based on the nonradiative dielectric waveguide. Widths of the main arm and subarm were determined experimentally. The T-junction was provided with a dielectric stub and thin-metal patches which proved to be effective matching elements in improving the performance. Well-balanced outputs in excess of -4 dB were obtained over a frequency range of 2 GHz at a center frequency of 35 GHz.read more
