In this paper, we propose a tunable CRLH ZOR based on the latest resurgent of ferroelectric materials. It is known that for most resonant structures, attainment of optimal performance requires some level of additional tuning through either mechanical means (i.e., with tuning screws) or other coupling mechanisms. Therefore, incorporation of electronic tuning into high temperature superconductor (HTS) material components without degradation of performance is very attractive. The result will be low-loss microwave components that could be¯ne-tuned for optimal performance, with the additional attribute of being tunable over a broadband frequency range. The dielectric properties of the ferroelectric thin¯lm, and the thickness of the ferroelectric¯lm, play a fundamental role in the frequency or phase tunability and the overall insertion loss of the circuit. The main driving force toward using the ferroelectric is the potential for substantial miniaturization of microwave components and systems and the potential for integration with microelectronic circuits due to the development of thin and thick¯lm ferroelectric technology. The ZOR is designed, and simulated by the full-wave analysis software. The response shows a variation of electromagnetic characteristics with the applied electric¯eld, ferroelectric thickness and the operating temperature.

“…This paper deals with the evolution of an electric fieldcoupled resonator for constructing metamaterial ZOR and presents a new planar broadband resonator with negative permittivity and permittivity. The simulation results of the above unit cell that included in [16] have been obtained by CST MW Studio compared with the experimental results are shown in Fig.3. As we see from the figures, measured results agree reasonably with those acquired from the full-wave simulations.…”

In this paper, we propose a tunable CRLH ZOR based on the latest resurgent of ferroelectric materials. It is known that for most resonant structures, attainment of optimal performance requires some level of additional tuning through either mechanical means or other coupling mechanisms. Therefore, incorporation of electronic tuning into HTS components with-out degradation of performance is very attractive. The result will be low-loss microwave components that could be finetuned for optimal performance, with the additional attribute of being tunable over a broadband frequency range. The dielectric properties of the ferroelectric thin film, and the thickness of the ferroelectric film, play a fundamental role in the frequency or phase tunability and the overall insertion loss of the circuit. The ZOR is designed, and simulated by the full-wave analysis software. The response shows a variation of electromagnetic characteristics with the applied electric field, ferroelectric thickness and the operating temperature.

“…These resonators are generally realized using microstrip technology where they can be implemented in different shape and size such as transmission line [10], radial [8], ring [3], [9], metamaterial [11] and coupled line [12]. As described in [13], the operation of RF/microwave resonators is very similar to that of the lumped-element resonators of circuit theory, whereby it can be modelled either as a series or parallel resistor, inductor and capacitor (RLC) resonant circuit.…”

In this paper, an analysis of open stub resonator is presented and its application in dual isolation band of Single Pole Double Throw (SPDT) switch is proposed. A mathematical model and the characteristic of the bandstop of the resonator were analyzed and discussed. The open stub resonator was implemented using the microstrip transmission line and able to switch between bandstop and allpass responses. Frequency bands of 2.3 and 3.5 GHz were chosen to demonstrate the dual isolation band in the switch design. The performance results of the SPDT switch showed that the isolation was greater than 30 dB, return loss was greater than 10 dB and insertion loss less than 2 dB at the center resonant frequency of 2.3 and 3.5 GHz. The potential application of the proposed dual isolation band of SPDT switch is for multi band RF front-end system such as WiMAX, LTE, WiFi and HyperLAN.
