In this paper, using common source topology, a 5 stages low noise and high gain amplifier has been designed. In the next section, an accurate model for passive components and transistor based on the measured S-parameters of each component have been derived. LNA design, optimization and simulated result has been presented in the last section.
A novel design strategy has been proposed for multiple antenna elements in MIMO systems to maximize the system capacity. Firstly, one single antenna has been effectively designed by HFSS software. Since it is very difficult to optimize the MIMO antenna parameters using HFSS, the single antenna has been modeled by a magnetic current to be used in optimization procedure. The magnetic current distribution...
We present a novel space mapping-based approach for the optimization of high frequency structures. A Cauchy rational function approximation with variable data tolerances is first constructed using the available inexpensive coarse model simulations. The parameters of the rational function are obtained through a fast linear program problem that is guaranteed to reach the global solution. The fine model...
A MIMO antenna design optimization method based on minimization of correlation coefficients for maximizing the system capacity in multiple-input multiple-output (MIMO) systems is presented. The packaging effects on radiation field patterns of MIMO antenna elements have also been included using a reciprocity approach and method of moments (MoM) analysis. As practical examples, optimal location of two...
We present a systematic approach for realization of multi-coupled radiators featuring an integrated filtering effect. Such procedure can be adopted easily either using an electromagnetic simulator, or when building antennas on the bench, by cut and paste techniques. This design routine significantly accelerates the development cycle, and alleviates the need for an exhaustive set of parametric trials...
The paper presented a general synthesis method that can be applied to guide the design procedure of many modern antenna/array problems. The technique is also useful in interpreting lots of measurement findings, and should facilitate the optimization process for enhanced solutions. A diversity antenna was designed and measured to demonstrate the capabilities of the proposed design methodology.
