Abstract

A modification of the conventional dumbbell-shaped coplanar waveguide defected ground structure (DGS) is proposed. This modification permits the continuous tuning of the rejected frequencies by using reconfiguration technique and it allows the control of the DGS equivalent-circuit model. The modified DGS possesses two-dimensional symmetry, hence, it has been studied under different symmetry conditions and the corresponding equivalent-circuit model in each case has been developed. Based upon this study, a tunable bandstop DGS resonator is proposed. 19% tuning range centered at 3.7 and 7.4 GHz, respectively, is achieved. The equivalent-circuit model of the resonator is also developed. All proposed structures have been fabricated. Measurements as well as three-dimensional simulations are found to be in a very good agreement with theoretical predictions. Index Terms--Coplanar waveguide (CPW), defected ground structure (DGS), tunable bandstop resonator.

10. Toward a simulation of an optically controlled microwave microstrip line at 10 GHz

Abstract

This paper deals with a microwave microstrip line that is terminated by a laser illumination, which alters the behavior of this microwave device. The first result is the numerical simulation of the microstrip line ended by a photoinduced load with the finite element method (FEM) and with hexahedral edge elements. The main difficulties of this kind of simulation remains in the fact that we deal with an open structure and that the photoinduced load is complex and inhomogeneous. Index Terms--Anisotropic and inhomogeneous complex medium, finite element method, optical control, photoinduced load.

Abstract

Frequency conversion in fiber-optic systems like subcarrier multiplexed (SCM) systems is now to be used in many applications for both digital and analog signals. The performance of two different optoelectronic configurations, both used for frequency conversion in the microwave frequency range, are compared here. In the first case, mixing is achieved by a Mach-Zehnder (MZ) interferometer, while in the second case, photodiode mixing is presented. Experimental investigations are presented at the optical wavelength of 1.3 [[micro]meter]. In both cases, promising results have been achieved. Index Terms - Fiber-optic links, frequency modulation, generation of optical mixing, interferometers, photodiode mixing.

Abstract

The frequency tuning of a quarter-wave resonator using an optoelectronic control is reported. Sharp notch characteristics with a small decibel-insertion loss and tunable frequency with matching better than 45 dB are obtained by varying both the optical power and the dc bias. The measured frequency shift is more than 60% below the dark resonant frequency and is carried out without altering the shape of the response. The biased photoinduced plasma (BPP) loading the open terminated microstrip line is then analyzed by comparing microwave simulations and measurements. The deduced complex load equivalent to this biased photoinduced plasma is then confirmed by semiconductor simulations. Results show the great possibilities offered by this BPP load (BPPL), which can be easily and widely tuned by means of a simple optoelectronic control. The frequency bandwidth of tuning is limited by the geometrical parameters and may be extended to millimeter-wave operation. Index Terms - Microwaves, optical control, photoconductivity, photo-induced load, silicon.

Abstract

In this paper, coplanar waveguide filters with etched-ground stubs that have multiple behaviors are proposed. The response of a unit cell is a bandreject with one or more transmission zeros according to the number and the lengths of the stubs. A library of transmission line models is being built for the basic cells and then used for the design of more elaborated structures. The potential of these new topologies is highlighted by providing different filtering structures with interesting features: a second-order narrow bandpass filter, and two configurations for a lowpass filter with a wide stopband. All theoretical predictions have been verified by electromagnetic simulation and measurements. [ABSTRACT FROM AUTHOR]

Abstract

A compact topology for bandpass filters based on coupled slow-wave resonators is demonstrated. A study of fixed band-pass filters leads to design rules and equations. Measurements on a 0.7-GHz fixed bandpass filter, consisting of three coupled slow-wave resonators, demonstrate the validity of the proposed topology and validate the theory, since the agreement between simulations and measurements is very good. Designed for a Q-factor of 5, this filter shows a Q of approximately 5.2. At the center frequency, insertion loss is 0.6 dB and return loss is greater than 20 dB. A 0.7-GHz tune-all bandpass filter is also designed and tested. The performance of this electronically tuned filter, which incorporates semiconductor varactors, is promising in terms of wide continuous center-frequency and bandwidth tunings. For a center-frequency tuning of ±18% around 0.7 GHz, the -3-dB bandwidth can be simultaneously tuned between ∼50 and ∼78 MHz, with an insertion loss smaller than 5 dB and a return loss greater than 13 dB at the center frequency. The surface areas of the fixed and tunable 0.7-GHz filters are, respectively, ∼16 and ∼20 cm². [ABSTRACT FROM AUTHOR]
