Hi all,
I am simulating a monopole antenna on the UAV. The UAV is about 4 [m] by 3 [m]. The monopole is put on the wing of the UAV, monopole is 70 [mm] long with a 1.5 [mm] diameter. Frequency is 1 GHz. When I try to mesh the structure, using the default mesh setting, an error occurred...
All right, no reply...
FYI, the problem is solved by using the incident plane wave + wave port/lumped port, after simulation use the field calculator to get the voltage on the lumped port. And from the voltage we can calculate the phase and magnitude information.
Hello Friends!
I am trying to simulate the structure in this paper: https://ieeexplore.ieee.org/xpls/abs_all.jsp?arnumber=5765478&tag=1
A quick question, I have two monopole antennas (#1 and #2) and use the plane wave as the excitation. I want to sweep the excitation angle (0-360 deg with 1...
Hi,
I used the following steps to export the CST structure to Altium.
1. CST export DXF file
2. use CAD open DXF and save as DXF 2000 version (only 2000&2004 version work)
3. use Altium import DXF and generate the gerber files
The elements have ring shape. But the problem is that the...
Hello all,
Anyone has experiences on this topic: reflectarray pattern optimization or phase-only synthesis? It is aim to decrease the SLL. I checked some papers, and some people are using Intersection approach, or GA algorithm.
I am wondering what's the procedure to do phase-only synthesis on...
Dr. Encinar's antenna structure is very complicated and I think he doesn't use the commercial software for the simulations. I dont have experience on multi-layer constructions. I think alignment is important?
In reflector antenna, usually we use horn as the feed. It has been checked that the radiation patterns of the horn can be simulated as a function: \[\cos\]^q (\[\theta\]) .
The power q has been chosen at each frequency to fit the horn patterns.
I already have the radiation gain pattern of one...
Thanks, Tallface!!!
I used CST for the array simulation, in the [farfields] results, it gives like following:
I polted all the abs, theta, phi, left, right data. The gain theta vs gain phi has a x-pol about -50 dB at broadside, but the RHCP gain is toally the same with the LHCP gain. I think...
Dear friends, :-D:-D:-D
I am still simulating a reflectarray using ring elements. For now I already got the pattern simulation results for the whole reflectarray. I am using rectangular waveguide as the excitation, instead of using feed horn, to simplify the structure.
Now my problem is: how...
Hi amanda
thanks for your information. I am curious about the 'parallel phase curve' you mentioned. Does parallel means linear phase curve?
Too steep phase curve means a tiny size changes will lead to a big phase change, so it will decease the gain and also the bandwidth. Is my understanding...
