Hi,
I am trying to plot the dispersion diagram for a transmission line metamaterial IFA antenna, consisting of a capacitor in series and an inductor in parallel to the antenna.
As far as I know, the dispersion diagram is the plot of frequency vs. phase of S21, as phase (theta) is beta*length...
Hi,
I have a new microwave resonator that resonates at f1, 2f1, 4f1, 5f1, 7f1, 8f1, ...
Please note that 3f1, 6f1, ... are missing out!
I want to model it using transmission lines.
Can somebody help me?
Regards,
Suhas D.
Thank you Volker for replying!
My antenna is designed for laptop applications. It is a folded PIFA.
The image attached shows you a sketch of what it is like.
Why does an antenna radiation pattern become multi-lobed and directional, when the length of the ground plane is increased?
1. Does it increase the electrical length of the antenna?
2. Does an increase in ground plane lead to more reflections, leading to a more directional pattern?
3. How can...
Hi,
We know that if an antenna is circularly polarized, its axial ratio is <3dB for the frequency range observed. Similarly what are the practical values for linear and elliptical polarization. Please don't provide infinity for linear polarization and very high value for elliptical...
