How to design paraboic shape in CST? just the reflector shape

i am planning to design a VSAT antenna.... i managed to make a horn antenna....now just need to add a reflector in front of this....Please can anyone describe me the geometry of Paraboic shape in cst? or what kind of extrude curve i have to use....this must be a great help for my personal projects. only the physical (...)

reflectarray antenna phase detection

hi antenna experts. i designed a Reflectarray unit cell with proper phase shift in cst. i used unit cells in array and fed it by a horn antenna. the solution type is integral equation. now i want to know how can i gain the phase of each element(phase of fields or reflection phase ) after feeding (...)

elements phase arrangement in CST (Reflectarray)

Hi all. I'm working on Reflectarray. i have designed my unit cell by cst. after designing the unit cell i placed the cells in array form and excite it with a horn antenna. now, each element have it's own phase in re radiating field. so we should know the element phases to compensate them to make all elements radiate in (...)

Why do I get back radiation when simulating this horn antenna??

Have you studied the currents on the outside surface of your horn antenna, particularly around the mouth of the horn? It sounds like you might have high currents that are leaking back onto the outer surface of your antenna, and these currents might be creating the radiation. I think there is a Field (...)

Planar near-field data from antenna in CST MWS 2014

Hi, I've set up a pyramidal horn in cst MWS 2014 with the following properties: Directivity: ~20dBi Design frequency: 10 GHz Waveguide measurements is standard EIA WR-90 x-band. I've simulated this with a E-field monitor and a farfield monitor and the plots for the farfield (...)

CST MWS VBA macro of e-field probe

Hi, everybody, i need all your help. I want to measure near-field of antenna, e.g. horn, like on the picture. 110917 and i need do it with a macro.110918 I used eField probe like here 110919 To measure all the aperture of horn, i need to use construction For...Next.

Design Pyramidal Horn using CST

Download the free evaluation of antenna Magus. The horn antenna is included. Just input your frequency range and click "design". You can then export the model to cst if you want and import there for further playing around.

Orange peel reflector antenna design

Can anyone help me for designing orange peel reflector antenna? I designed it with Integral equation solver in cst MWS software, but when i placed horn in front of a reflector and run it in transient solver, patterns are lost. I do not what can i do, Please help meeeeee I needed it very soon my email:

interval modification in cst simulation

actually i have no idea about waveguide mode. i am a beginner user for cst simulation. do u mean that i just simply need to right click at port part and increase the number of mode to 2? "the exist hybrid modes at inhomogenous port 1. this could lead to an inaccurate energy balance. please check your structure">>> i got this error after increase th

How import points from Matlab to CST?

Hello there, I want to simulate ridged horn antenna in the cst. I have an analytic equation that describes the ridges and I want the Matlab will plot me the points that realize the equation and import them to the cst.How can I do it? TNX.

problem in designing slotted waveguide antenna using CST software

Hiii everyone,i am doing a project on slot antennas using cst software but i don't know how to feed the waveguide.could anyone please tell me the design and simulation procedure for slotted waveguide antenna.thamq in advance... REGARDS PICSA !!!!

CST simulation Problem

Hello forum, I am new with antenna and cst, sorry if there are some stupid questions; In fact, I have a mini-project about simulating a pyramidal horn antenna, I don't know what exactly do, and what parameters should I play with to enhance the horn's gain, A great thanks (...)

Problems in CST: Frequencies in Port1 and Port2 are not compatible

Hi Dear Members, I have some problems in simulation of a horn antenna in cst. Frequency range: 27.9-28.1 GHz R_port1= 7.15 mm Result: operating frequency at excited port1: 29.4 Ghz operating frequency at output port: 28 GHz This is my model 59690 What happens with operating frequency of wave at excit

design Reflectarray by CST

HI everybody!!! My thesis is to design single layer RA by cst. Indeed I start to use cst 2 days ago and really I am completely confused by many settings on it :sad: Could anybody tell me the steps to design unit cell and get phase plot??? and how to feed by horn??? I appreciate any (...)

cst microwave integral solver problem with metalic loss

Hi, I'm using cst microwave integral solver to study lens antennaes. When i tried to analyze a PEC feedhorn its all ok, but making it a lossy metal one makes Directivity < Gain :S and that's clearly wrong for example taking the horn from the macros, MACRO>Construct>Online>horn (...)

Horn Antenna in CST MWS 2009

Hi everybody, I'm trying to construct a pyramidal horn antenna in cst microwave studio 2009, just don't know how to start the drawing. Anybody can point me to the right direction on how to construct a horn antenna by providing some link, tutorial or even simple instruction? Any suggestion will be (...)

Reflect Array Antenna on HFSS

it's not possible with HFSS but you can simulate a 24cm*24cm relectarray in X band in cst with the horn feed.(using symmetry plane)

how i plot field in any position in cst?

hi all,i have little question of cst how can i polt the field of any antenna at any position(not near field nor far field) i make horn and put probe in my desired postion ,so how can i measure field I(i.e. how could i rotate the probe to measure the field pattern ) i wait so fastly ur reply

CST MWS 2006 Horn Antenna Help Required (Basics)

Hi I am just trying to learn cst MWS 2006. I have modelled a horn antenna which is already realised. The antenna resonates at 15GHz. I have assigned a waveguideport to the antenna. But I am finding almost entire signal being reflected. I request you to kindly try to locate the problem. I feel I have (...)

CST Question for Micro machined antennas (Mesh Problem)

Hi, First of all I want to thank to ?plasma?. I attached two files whose names are "ydene7r3" and "ydene7r4". In the files we have horn antenna exciting at port 1 and the micromachined antenna in front of it. In "ydene7r3" there is single antenna (made of gold) and (...)

a question about conical horn antenna

usually, ad hoc software simulators will solve the horn analisys for TE11 fed horns. Advanced and expensive simulators like hfss, cst may take in consideration high order modes. But generally the fundamental, TE11 mode is looked for and wanted. Higher modes are used to build the monopulse radar but the (...)
