Ansoft HFSS and CST have much better interface which enable te user to include very fine details in the geometery of simulated structure. The difference is CST consumes less time and gives you the approximated results as it is based on Finite Integral Method (FIM), whereas HFSS take more time but will provide you with accurate results as it is based on Finite Element Method (FEM). For instance, I have seen that measured results of UWB antennas closely agree with CST. Different opetions are found in HFSS, but it is still FD solution. HFSS is high value EDA solution that greatly reduces engineering time investments for high frequency designs. After that, you need to provide three more parameters named Average wire size, Number of elements, and Frequency. ADS 2009 is based on Moment method but in ADS 2011 both of FEM and moment method are supported. The best software that i reccomend you is HFSS. Journal should be SCOPUS or SCI indexed. It is used to design J-pole antennas for the desired frequency. Can be interfaced to HFwin32 propagation prediction software. Results are not worse than obtained in HFSS. Plus, it lets you calculate the wiring, elements, and boom lengths for a perfectly arranged antenna. A cheaper option from CST, especially if you're not able to avail of the student version of CST or even Ansoft HFSS is Efield, from. This diagram may help you understand the design of a multiband J-pole antenna better. Antenna modeling, especially in Amateur Radio. This software can not only be used to design but also to find out antenna gain, stacking distance, and Standing Wave Ratio (SWR). This type of antenna mainly contains two connected passive elements that give this antenna a rectangular look. 4NEC2 antenna modeler pop - 4nec2 is a completely free Nec2, Nec4 and windows based tool for creating, viewing, optimizing and checking 2D and 3D style antenna geometry structures and generate, display and/or compare near/far-field radiation patterns for both the starting and experienced antenna modeler. In the result, you get Element length, DIA (diameter), and Spacing values for an antenna of elements up to 12. Passionate about tech and science, always look for new tech solutions that can help me and others. The advantage of CST is that within on run one can obtain the results on a wide band because it starts in time domain and convert the results to FD via Fourier Transform. Moment method is also referred to a low frequency asymptotic. Transmitting and receiving antennas can be designed and several antenna parameters can be obtained as a function of frequency: input impedance, standing wave ratio (SWR), efficiency, radiated and consumed powers, gain, directivity, beamwidth, front to back … It is mainly used to design Quagi antennas. Actually, first of all one should choose the best EM Numerical Method for his/her project based on "bandwidth" and "electrical size", this can be classified as follow: -B.W high(order of hundred MHz and GHz), Elsize large(order of 10lambda and more) : FDTD(superior), TLM, -B.W low(order of MHz), Elsize small(order of 2lambda and less): FEM, -one frequency, Elsize large,PEC structure: MoM(IE), -one frequency, Elsize very large(order of 300lambda and more),PEC structure: GTD. Again - making a UI would be a great weekend project if anyone's looking. If you only want a quick design over a predefined modelyou should try Antenna Magus. FEKO and Designer are particular suitable for frequency domain analysis, then you can use CST it performs a time domain analysis then convert it into a frequency domain, the GUI is not so easy and in my opinion it provides result with less accuracy with respect to the others software. Yagi Calculator is a free antenna design and analysis software for Windows. Using this software, you can find out antenna’s maximum Mesh size, Gain, Beamwidth, and X/Y coordinates to design the antenna accurately. Actually, I have got one review on my research paper that, I need to show the simulation result upto some range. If the antenna is planar with an infinite ground for me, the best one and quick one in simulation is ADS " Advanced Design System". (depends on the frequency they work) --please do help. Some software yield better results based on specific applications. I think that FEKO and CST Microwave Studio are the most powerful software tools in the design of antennas. Cost: Freeware MMANA is an antenna analyzing toolbased on the moment method introduced in MININEC (Mini Numerical Electromagnetics Code) Version 3. HFSS is mostly used for Antenna design. All these menus can be accessed from the Task drop-down menu. For planar structures such as rectangular, circular etc patches even along with some perturbation IE3D simulation software is the best and it can be very easy for users. As with any multi- element antenna, parasitic elements load the driver, therefore, lowering feedpoint impedance due to mutual coupling. L B Cebik, W4RNL has a very good book on antenna modeling and has some antenna modeling software listed on his web site. AN-SOF is an innovative software tool for the modeling and simulation of antenna systems and general radiating structures. When the size of the radiating object is larger than wavelength, high frequency asymptotic techniques can be use for analysis. AC6LA Software. However, the responses were quite interesting and I am also in confident with them in terms the CST, HFSS and IE3D that are well known and proved their usefulness including others useful codes in which some of them use hybrids methods. General Concept information about Microwave design softwares? Inderprastha Engineering College, Ghaziabad, if you have knowledge of boundry condition of field distribution then u may use CST or HFSS both give same. This type of antenna usually contains multiple elements of different lengths and spacing between each other. CST studio is another electromagnetic simulation software which lets you to deal with any type of antennas (microstrip to reflectory antennas) and it is based on The Finite-Difference Time-Domain Method (FDTD). Above: Screen shots from several EZNEC v. 6.0 displays.Right: 3D far field pattern, with 2D elevation "slice" highlighted. I find it far faster for initial entry than X-Y-Z entry of coordinates. The Advanced Design System (ADS) software is one of strongest CAD softwares. In this freeware, you cannot save the parameter values, but you can still copy the values to the clipboard and save it as a text. For the design of antenna modelling such as for patch antennas, IC designs, waveguide systems and even feed horns, though they should be electrically small, I would agree with Marrco Azpurua with CST, and the Antenna Magus tool is quite nice. The FDTD cannot be used in eddy current. In general, for antenna simulations CST is preferable. Here is a good place to see different softwares and some comparisons: Cochin University of Science and Technology. AutoEZ works in conjunction with the EZNEC antenna modeling program and allows you to use variables to control diverse aspects of the model. for example if you want to simulate a microstrip antenna whit finite element method, I think the best and easiest choice is Ansoft HFSS. but it is high cost ,so we can go for ZEMAX, The Zeland IE3D software is easy and user friendly.
