Help me define the plane-wave excitation and set dipole as receiving antenna in IE3D
in ie3d, can i define the plane-wave excitation and set a dipole as receiving antenna, so to get different current distribution with different load?
I had try in this way: first, finish the geometry of dipole and define a Horizontal Localized Port in Dipole along with a Plane-Wave Excitation and run; Second, in modua i define the lumped element (say 50 Ohm) in Horizontal Localized Port and run, but ie3d prompt that there is no port.
Thanks in advance !
You certainly can do it. What you need to do is to define a port and define planewave excitation. You can save the .cur file or even setup for .pat file calcualtion with specified excitaiton and terminations. If you want to have planewave excitation and the port to be terminaed with a load, you can define the load at the port while there is no source on it. In this way, you will be able to find the voltage and current at the port. In fact, for the latest ie3d 11, you will get the .mpa file which allows you to define the excitaiton and termination for the port and the planewave easily at the post-processing time.
Dear jian,
Among the port parameters, does Zc means the characteristic impedance of the transmission line linking the source and load? And why Zc and Zs should be specified when define the plane wave source parameters?
Thanks!
Hi, Wusen:
When you define plane wave and ports together, we will need to know the excitation and termination at the ports when the plane wave is applied. Zs is certainly needed. You should consider Zc as the normalization impedance. On IE3D, you can re-nromalize it to any Zc (real value) and it is not necessary to be the characteristic impedance of the line. The normalization impedance is needed if you want to find the incident wave and reflected wave with respect to the normalization impedance.
