摘要
A novel millimetre wave wideband time delay line based on substrate integrated waveguide (SIW) is proposed in this article to achieve true time delay. The delay line is formed by loading the SIW with cross electromagnetic bandgap (EBG) unit. The higher delay time can be obtained by adjusting the structure size without affecting its transmission characteristics. A simulation software HFSS is utilised for the optimisation to achieve a better performance. ,, delay lines have been designed and measured in Ka band. All delay line is implemented in this article in Rogers Duroid5880. Compared to the microstrip of the same length, the average delay time is about four times of microstrip on the same substrate in the whole bandwidth from 27.7GHz to 37.7GHz. The simulation and measurement show good consistency.
