Real time signal retention device using co-planar waveguide (CPW) as Mobius strip

In this paper, we show that two back to back coplanar waveguide (CPW) in the form of Mobius strip has resulted in an infinite transmission line capable of retaining a large bandwidth of frequencies that can be useful for real time signal retention device (RTRD). By providing Mobius twist to CPW, a continuous phase change reported instead of abrupt phase change by using shorting pins between two parallel transmission lines. It is observed that the device retains the injected signal in time domain over a broad band of frequencies. The signal can also be a pulsed signal as in Ultra Wide Band (UWB), or a modulated microwave signal, can retain transient signals encountered in Radio Astronomy, Medical applications and many more exciting applications.
