Abstract

This paper presents a delay line element with meandered slots being part of a substrate integrated waveguide (SIW) structure and its numerical analysis. The proposed delay line element is designed by using a coplanar waveguide (CPW) configuration due its low dispersion compared to other transition configurations. The proposed delay line element is designed on a substrate of Rogers RO4360 with a thickness of 1.524 mm. Its numerical characterization is conducted in terms of return loss, insertion loss and group delay time. By numerical analysis and synthesis, the optimum delay line element can be designed and the desired characteristics can be achieved for operation in the frequency range of 1.4-2.8 GHz with a return loss up to 40 dB at a frequency around 1.75 GHz. Additionally, an almost flat insertion loss with values around 0.5 dB and a likewise nearly constant time delay around 1 ns is achieved over the desired frequency band.
