In this paper, we introduce an electronically tuneable band-stop filter based on a dielectric resonator, along with its design principles and equivalent circuit model aimed at the coexistence of intelligent transport systems (ITS) and cellular vehicle-to-everything (C-V2X) communications operating at 5.9 GHz, with the widely spread vehicular dedicated short range communications (DSRC) at 5.8 GHz. The proposed architecture involves a dielectric resonator coupled via a microstrip transmission line to a planar ring resonator. The resonance is electronically tuned by varying the bias voltage of a varactor diode placed in the ring. This design is analyzed theoretically and experimentally. For validation, a filter operating at 5.8 GHz was designed. The prototype is capable of enhancing coexistence exhibiting to features. First, when inserted into the ITS transmitter chain, it reduces unwanted transmitter emissions in the out-of-band spectrum occupied by the DSRC carriers in the 5.8 GHz frequency band of at least 25 dB, with a minimal insertion loss at 5. 9 GHz of 1.6 dB; secondly, when inserted in the ITS receiver chain, it exhibits high linearity that prevents the generation of intermodulation products falling into the filter pass band. The prototype features more than 21 dBm of third-order input intercept points, and a tuning range of 26 MHz while maintaining a minimal loaded Q factor of 93. The prototype is discussed regarding the detailed equivalent circuit parameter extraction and their dependency upon the control voltage.

Scattering parameters of microstrip ring resonators (with and without slits) that are either edge or side coupled to the feedlines are simulated by the FDTD method. The strip conductors on the device can either be infinitely thin or finite in thickness. The simulations predict the occurrence of resonance peak splitting due to the simultaneous existence of magnetic and electric field coupling mechanisms. Excellent agreement was obtained between the simulation results and the measured data for a ring resonator. We have also shown that it is possible to use finite‐difference time‐domain simulations to determine the dielectric constant of substrate materials. © 2000 John Wiley & Sons, Inc.

The modulation of a microwave‐scale Mach‐Zehnder interferometer coupled to a dielectric resonator (DR) tunes the DR resonance frequency. We report on a theoretical study to develop an understanding of the intrinsic tuning properties of an Mach‐Zehnder interferometer ring‐DR‐microstrip line system and present an experimental verification. © 2013 Wiley Periodicals, Inc.
