To protect devices from interference and solving the problem of electromagnetic compatibility, it is necessary to use filters with attenuation of 60 dB and more in the bar. annotation scientific article for electrical engineering, electronic technology, information technologies, author of scientific work - Derachits Dmitry Sergeevich, Kisel Natalya Nikolaevna, Grishchenko Sergey Grigorievich Therefore, in PHI = 0, the Theta is changed from 0-180, the corresponding surface is an Xoz surface, that is, the E side, as shown below.Keywords High frequency filter / Cutting frequency / BANDWIDTH / CST Microwave Studio / High-Pass Filter Cutoff Frequency / Bandwidth. Through the field monitor, it can be seen that the E side is cut along the Xoz (faces parallel to the current direction), and the h is cut along the Yoz.

You can also view the direction of the polar coordinate form, click Polar.

It is already built here, and the antenna simulation is performed below.ġ Check if the three are correct: frequency, background fill (peripheral square box), boundary (default is infinite, no reflection)Ģ, check the Mesh grid, especially the boundaries of different materials, see if there is a split grid.įor example, in the X direction, the same material and continuous, cut into three meshes, meet the requirementsģ, simulation to the antenna time, waiting for a moment Third, the simulation results of the antennaĢ, the direction map, about 2.3G Hz in the resonance point. The parameters are as follows: Generally selected as three times the thickness, while the bottom surface is attached (double TS) Press f to select the feeder surface, click on Waveguide Port, you can generate the need for the feeder! Here we choose the second The parameters are as follows, pay attention to select the PEC material!Ĩ, port settings, there are two methods: 1, click on the WAVEGUIDE PORT, there will be a big plane in the peripheryĢ. Regenerate a side of the button! Choose one ground first Where w = 1.46ħ, GROUND modeling, press F Click the bottom surface, then click the regeneration, the operation, the parameters are as follows.

Third, the simulation results of the antennaġ Select Patch, will give a corresponding unit after the selection.ģ Select the corresponding operating frequency range, select the corresponding monitorĤ, establish a substrate model, select Brick, set x, y, z value, select the substrate material, where LX, Ly, TS value is as followsĥ, set a patch model, select Brick, parameter as follows.Ħ, feed line modeling, select Brick, parameter settings are as follows.
