PROJECT TITLE :

Ultra-wideband short-pulse power divider based on coplanar waveguide and slotline structure

ABSTRACT:

An ultra-wideband (UWB) short-pulse power divider with a unique structure utilising the coplanar waveguide (CPW) and therefore the slotline transmission line is presented. The novelty of the proposed design will be manifested by that the electromagnetic energy propagates along the 2 slots of CPW can be naturally divided into the two slotlines of the output ports. The resistors bridging the 2 slotlines are applied for smart isolation and return loss performance. The simulated and measured results for the fabricated prototype gift an ultra-wide frequency band from zero.sixty five to 7 GHz, where come loss the least bit the ports and the isolation between output ports are higher than 10 dB. The performance of the proposed power divider is additionally characterised by time-domain short pulses, which shows that the power divider is featured by terribly high fidelity and low dispersion for brief-pulse applications.
