How to design a Yagi-Uda Antenna using CST Studio Suite

Here in this video we'll show you how to design a Yagi-Uda Antenna using CST Studio Suite. This tutorial will comprise of a series of videos one after the other please do check those for better understanding. Link of the video “How to design a Dipole Antenna“- & simulate Dipole Antenna us... Step 1: Open the previous project created for dipole antenna in previous video. Step 2 (creation of director): Go to modeling then select cylinder and press escape in your computer and following window will pop up. As the radius of the cylinder is 2.5 mm and the material is chosen PEC, then edit as shown in the video. Step 3(creation of reflector): Go to modeling then select cylinder and press escape in your computer and following window will pop up. As the radius of the cylinder is 2.5 mm and the material is chosen PEC, then edit as shown in the video. Observe- The final 3 element Yagi-Uda array will appear. Step 4: Go to simulation and then set up solver. Then start simulation. After the simulation is over, observe S11 from the navigation tree. Observe- that the antenna is resonating at 1 GHz. Step 5: Go to navigation tree then 2D/3D results, then right click on farfield (f=1)[1], then following window will pop up. Do the settings for E field pattern as shown in the OK to visualize the E field pattern. Observe- that half power beam width is near to 64.4 deg. Step 6: Go to navigation tree then 2D/3D results, then right click on farfield (f=1)[1], then following window will pop up. Do the settings for H field pattern as shown below. Press Apply and OK to observe the H field pattern. Observe that we get a directional radiation pattern in H plane unlike simple dipole HPBW in H plane is 99.8 deg. Step 7 (Determination of directive gain): Go to post processing, then result template. In the result template, choose “Farfield and Antenna Properties“ and “Farfield result“ from the drop down menu. Then a window titled “Farfield Result“ will pop up. Then go to All Settings. Then following window will pop up. Then do the necessary changes as shown. Also click on Plot Mode in the following window and check the linear scaling. press template will now appear in “Template Based Post Processing“ window. Click on Evaluate to get the following result. Observation: Directivity of the simulated Yagi-Uda array is 5.6 which is much higher than dipole antenna simulated in previous experiment at 1 GHz.
