thank you jiripolivka & biff44, i still don't get the idea,
i'm working on smart UWB antennas, and i want to study them in time and frequency domain, just theoretically, so until now, i didn't understand how to do this properly
if u have any idea, or exampls, please show me
i will be so grateful
about time and frequency domain
Hello!!
i want to understand, what do we mean by studing or characterize an antenna in Time domain and frequency domain
thank you
Thank you so much for the answer, but i still have problems even when i used integral solver
an error message keep telling me "error in mesh generation. out of memory - could not generate mesh".
well my mesh properties as it is mentionned are :
steps per wavelength = 3
Min. number of steps =...
Good evening,
please help me
can we simulate an antenna in an environnement with CST MWS?
i did this, but i keep get a error message telling me tha the mesh is too dense, i tried to change it, so after that i got a error message telling me that the solver is exhausted and abort
how can i do...
thank you so much for the helpful answer
- if you allow, can you please telle me what is the diffenition of fractional and relative bandwith that you have
- and i'm working on UWB (3.1 - 10.6 GHz) bandwidth, and i read definitions about how to calculate and consider this bandwidth as an UWB...
Good morning,
i have problem with few definitions, and i will be so grateful if someone can help me,
i really want to know:
1. what is the difference between the fractional and relative bandwith ? (some books said there is difference and some books said that they are the same)
2. why we...
Hi ...
i designed a small U-slotted planar antenna for IR-UWB, and i have probleme with the port impedance, i don't get 50 ohm in the input, i can't touche the design parameters , so i am wondering if the probleme is in the simulation parameters.
please help me
thank you so much for helping me
yeah, i found the equation of balanis, but i found other equations also to calculate the input impedance in other books, as the one in "Antenna Theory and Microstrip Antennas", D. G. Fang
this why am so confused
and each one gives a different results, even...
maybe, i didn't good explain the probleme
1. am new on CST, so at first i want to design a simple rectangular antenna, but i have problems with that
2. the monopole antenna in the pic is not the one that i want, but another one similar designed by Mr. Tan Phu Vuong : Design and characteristics...
