Although from different computer-aided design (CAD) software vendors, most of their optimizers follow the same idea: embedding various kinds of general purpose optimization methods and connecting them with their EM simulators. MathWorks has also provided an antenna toolbox since 2015 using MATLAB optimizers to perform antenna design exploration. are major tools for antenna design engineers to perform design exploration.

The proposed methods mainly include employing traditional derivative-based and derivative free methods ( Bandler et al., 2004), as well as employing evolutionary algorithms ( Hoorfar, 2007).ĭue to the importance of design exploration in electromagnetic (EM) device design flow, these research products are transferred to commercial software tools rapidly. Over the last decade, a number of research works have been carried out on this topic, providing useful results. Antenna design exploration aims to obtain optimal geometrical design parameters optimizing (a) design objective(s) and/or satisfying design specifications based on a given antenna structure.

In recent years, design exploration or design optimization has replaced the traditional trial and error method and has become a standard step in the microwave antenna design process. A case study verifies the advantages of ADE.Īntenna design optimization, Antenna synthesis, Surrogate model assisted evolutionary algorithm, Multiobjective optimization, Software tool 1 IntroductionĪn antenna is an essential device in satellites, automobiles and many electrical machines. The key features are: (1) State-of-the-art antenna design exploration methods are selected and embedded, addressing efficient antenna optimization (critical but unable to be solved by existing tools) and multiobjective antenna optimization (not available in most existing tools) (2) Human-computer interaction for the targeted problem is studied, addressing various usability issues for antenna design engineers, such as automatic algorithmic parameter setting and interactive stopping criteria (3) Compatibility with existing tools is studied and ADE is able to co-work with existing EM simulators and optimizers, combining advantages. Aiming to fill the gaps, a new antenna design exploration tool, called Antenna Design Explorer (ADE), is presented in this paper. However, these general purpose optimizers are facing challenges in optimization efficiency, supported optimization types and usability for antenna experts without deep knowledge on optimization. Good agreement is found between the measurements and the simulation results.Optimizers in commercial electromagnetic (EM) simulation software packages are the main tools for performing antenna design exploration today. The experimental measurements are done using the vector network analyzer (VNA HP8719Es). The fabrication is done using thin film technology and photolithographic technique. The antenna elements and the array are realized on the FR4 (lossy) substrate with dielectric constant ε r = 4.5, loss tangent of 0.025, and height h = 1.5 mm. In addition, a design for ultra-wide band (UWB) antenna element and array are introduced. The power divider is realized on Rogers R03010 substrate with dielectric constant ε r = 10.2, loss tangent of 0.0035, and height h = 1.28 mm. The design of the antenna array and the power divider are made using the software package CST MICROWAVE STUDIO. These matching techniques are used to adjust the branches impedances according to the desired power ratio. The amplitude and phase of the signals emerging from each power divider branch are adjusted using stub and inset matching techniques. A new design for a four ports unequal circular sector power divider and its application to antenna array SLL reduction is introduced. For the synthesis of a radiation pattern, an unequal-split power divider is required. A power divider can be utilized as a feeding network of an antenna array. Power dividers play a vital role in various radio frequency and communication applications. The proposed antenna array system consists of two main parts, the antenna array, and its feeding network. In this paper, the hardware implementation of an antenna array system for SLL reduction is introduced using microstrip technology. This interference reduction increases the capacity of the communication systems. It is considered as one of the most important applications of digital beamforming since it reduces the effect of interference arriving outside the main lobe. Side lobe level (SLL) reduction has a great importance in recent communication systems.
