    CST Antenna placement using calculated near field source

    Hello, I would like to compare results from simulations of antenna mounted on UAV using Transient Solver and Integral Solver. For Integral I will use recorded near field source (simulation of antena placed on infinite groundplane in transient solver). Do You have any experience with nf box...

    CST bounding box size manipulation

    Go to boundaries and set all boundaries to "open", without adding space. Now You can control the domain size by the size of Your vaccum box. Regards

    How to design an antenna to operate at 3 and 5 GHz?

    Try smaller patch dimensions.

    <cst mws/ds 2011> Optimizing patch antennas placement

    Thank You. I used inacurate terms in my thread. Of course it's about beam shapeing. The main case is that i can simulate situation when both antenna elements are excited simultaneously so i can archieve gain of the complete antena system. One more time thanks mr Kafeman for Your reply.

    CST Microwave 2010 warning: degenerated mode at port1 not considered in time domain

    Hi If you're using waveguide port as excitation try to change port dimensions . Search "waveguide port overview" in help. Hope that helps

    <cst mws/ds 2011> Optimizing patch antennas placement

    I'm working on optimization of six patch antennas placement on a larger structure. The goal is achieve best gain in all directions without "blind" areas. I'm using cst 2011 at school with uni license ( no A- solver and other limitations). I read papers from cst site about antenna placement...

    <CST> 4 way wilkinson on flexible structure - bend sheet functi

    Hi, design has been improved since last update. Fully functional model has been built and measured with good results. I can't upload .cst files cause my whole work is property of my school. If you need 4 way Wilkinson with equal split on conventional laminate it's really easy case. My work was...

    <CST> 4 way wilkinson on flexible structure - bend sheet functi

    Thanks for answer. Ad. 1. Thanks , I will try to change the strip design . This power splitter works in narrow bandwidth like 2.4 - 2.4 GHz . Ad. 2. I can do it when I'm using waveguide ports and there is no need to make a free space boundaries. When I'm bending the structure I need to...

    <CST> 4 way wilkinson on flexible structure - bend sheet functi

    Hi I'm designing an 4-way wilkinson power divider with flexible structure. After successful optimalisation I would like to simulate change of S-parameters when you're bending the whole structure. The problem is when I'm bending the structure on cylinder the microstrip line partially isn't...
