With the spectrum more and more overcrowded, filters and duplexers are drivers of the technology in the discrete device mobile market. The user segment of wireless communication systems leverages the outstanding performance of filtering devices based on acoustic wave resonators. But so far, these technologies have not covered the rest of the RF passive elements in a Front End Module. The use of Bulk Acoustic Wave technology overcomes the miniaturization issue. The acoustic technology exhibits key properties which allow a significant size reduction. In an RF-Front End Module, the passive devices are under continuous pressure to shrink. Some conventional power dividers are not adequate for the high level of miniaturization demanded. To contribute on the size reduction demands of dividers, we have studied two different topological designs which applies bulk acoustic wave technology. Specifically the two proposed devices are based on Coupled Resonators Filter structures. Guidelines for the design of both 3-dB power dividers are described on this paper. We illustrate the designs with two splitters based on the two topologies for application on W-CDMA and their simulated performances. Both dividers have embedded passband filtering responses and have all the ports matched. Furthermore, the designed splitters simplify the fabrication of CRF because almost all the multilayer films are uniform.

The probe is one of the major components building an indoor system for antenna near field measurement. In this paper, we present a geometric characterization of the Open Ended Rectangular waveguide and the pyramidal horn probes, used to measure the tangential component of the electric field. The results obtained show that the field and the voltage are proportional to the dimensions of the probes. They increase with the parameter h and they pass through a maximum for the parameters Psi and Pci.

This paper presents a simple and powerful design of a closely C-shaped microstrip patch antenna for wireless access in vehicular environment. Other wireless technologies such as WLAN, WiMAX, C-band, 5GHz U-NII, X-band and Ku-band applications are also supported. The microstrip patch antenna has been designed on the FR-4 substrate of 4.4 and thickness of h = 1.5mm, with a whole dimension of 25mm × 22mm. The proposed antenna can synchronously operate in multiple frequencies, covering four bands: [2.3538GHz-2.5388GHz], [5.0243GHz-8.0607GHz], [9.2403GHz-10.595GHz], [12.67GHz-15.182GHz]. To being small size, the new antenna exhibits stable far field radiation characteristics in the entire operating bandwidth with a relatively high gain, especially in the broadside direction which is suitable for vehicular systems. Using a full wave electromagnetic commercial simulator CST, a comprehensive study is detailed to understand the characteristics of the antenna in terms of electrical performances by considering reflection coefficient, radiation patterns, gain and VSWR. Results show, that the antenna is suitable for multiband wireless communication systems.

In this contribution we introduce an approach to analyze and detect the formation of Brillouin precursor in a signal propagated through a dispersive vegetation for the frequency band of 2.4GHz. We theoretically predict he evolution and formation of the Brillouin precursor for an ultrawideband waveform: the trapezoidal pulse. The pulse setting allows it to vary between two extreme shapes: rectangular and triangular, by prospering configuring the slope of the trailing and leading edges. We analyze the influence of the pulse setting on the precursor formation.

In this paper the design of an ultra-broadband six-port reflectometer, operating in an over-decade frequency range is presented. The proposed modifications of the classic solution have allowed to significantly increase the operational bandwidth and to ensure the stability of the reflectometer performance in terms of frequency. Moreover, an improvement allowing to eliminate the seventh, unused port has been proposed. The presented six-port reflectometer has been experimentally verified by reflection coefficient measurements of several reflective elements in a frequency range from 0.5 to 5.5 GHz, showing a very good agreement with the results obtained using commercial VNA.

This paper proposes the realization of a three box parallel nonlinear model for predistorting a switched mode power amplifier (PA). Such amplifiers are highly efficient but exhibit very strong nonlinear effects, and this constraint has considerably limited their use. Through the implementation of accurate models as the predistorter, the nonlinearity inherent in the switched mode power amplifier can be compensated for. Driven by a wideband signal, simulations show that the model used achieves an improvement of 1.224dB in the adjacent channel power ratio (ACPR). Overall, the PA maintains 71.3% power added efficiency (PAE), a significant increase over other classes.

In response to the growing demand of broadband wireless access, the WiMAX (Worldwide Interoperability for Microwave Acces) technology has emerged as an alternative to the wired broadband access solutions. It provides an Internet connection to broadband coverage area of several kilometers in radius and incorporate several quality of service (QoS) mechanisms at the Media Access Control (MAC) level for guaranteed services like data, voice and video. Unlike DSL (Digital Subscriber Line) or other wired technology, WiMAX uses radio waves and can provide Point-to-Multipoint (PMP) and mesh modes. In parallel, it can be noticed that in contrast of the usual quality evaluation approaches, nowadays, current researches focus on the user perceived quality, the available scheduling approaches take into account the QoS and other parameters, but do not consider the Quality of Experience (QoE). In this paper, we propose a QoE-based scheduling solution in WiMAX network in order to control the packet transmission rate so as to match with the minimum subjective rate requirements of each connection, this makes the scheduling based on the use of QoE metrics. The target of this improvement is to schedule traffic of the Unsolicited Grant Service (UGS) and the Real-Time Polling Service (rtPS) service classes. Simulation results show that by applying various levels of mean opinion score (MOS) the QoE provided to the users is improved in term of throughput, jitter, packet loss rate and delay.

In this work, we introduce a high precision cascade synthesis technique for lossless matching networks involving Brune and Darlington Type-C sections. In the present manuscript, we generalized our previously introduced high precision LC-ladder synthesis algorithm to include the extraction of finite real frequency and right half plane (RHP) transmission zeros of an impedance function as Brune and Darlington Type-C sections respectively. In the modified synthesis algorithm, after each finite frequency and RHP transmission zero extraction, remaining immittance function is corrected using a parametric approach. It is shown that proposed high precision algorithm can synthesize immittance functions of up to 40 reactive elements with accumulated relative error in the order of 10-1. The modified high precision synthesis package is developed in MatLab environment and it is integrated with the real frequency techniques to design high complexity matching networks over broad bands. An illustrative example is presented to exhibit the usage of the proposed high precision synthesis algorithm.

Flood is a major natural hazard in the world. For the period 1996-2005, about 80% of global natural disasters were meteorological or hydro. The floods have affected an average of 66 million people per year between 1973 and 1997. By these statistics, floods are considered the disasters that produce the most damage. Thats why we must handling floods data with great caution since human life is at stake. In this paper, we present an intelligent model that gathers data received from the wireless sensors and reach them in an intelligent way on one hand, on the other hand, it detects erroneous or redundant data to classify them to just have reliable and adequate data to be stored in the database in order to be processed in the decision support system for real time flood forecasting by using of the multi-agent system (MAS) to process data, eliminate redundancy, non-useful and erroneous data and establish collaboration between mobile agents to send the results to the base station.

This paper compares three different resonant particles which are useful for the implementation of metamaterials, planar microwave circuits and microwave sensors, namely, split ring resonators (SRRs), electric-LC (ELC) resonators, and S-shaped split ring resonators (S-SRRs). The three particles can be excited magnetically and/or electrically, under appropriate field polarization conditions. A transmission line, such as a coplanar waveguide (CPW), loaded with these resonant elements can be used as a rotation sensor, where the sensing principle is based on the variation of the notch magnitude with the orientation of the resonant particle. As compared to SRR-based rotation sensors, ELC-based sensors provide better linearity, sensitivity and dynamic range, although the electrical size of the ELC is larger. It is shown that the S-SRR combines the advantages of the ELC in terms of linearity, sensitivity and dynamic range, with an even smaller electrical size than the SRR. Preliminary results to demonstrate the potential of S-SRR-loaded CPWs as rotation sensors are provided.
