what's the E-plane and H-plane of this antenna?It's very urgent for me.

[project.email]

Dear friends
I attached the figure of an antenna and the far field radiation pattern.
I want to know:
1.what are the co-polar and x-polar pattern direction?
2. what are the E-Plane and H-Plane?

it's very urgent for me ,I really thank if some one help me.



The 2d figure is the Directivity as a function of Phi at a constant Theta angle that is Theta=90(deg)
The 3d figure is the Directivity as a function of Theta at a constant Phi angle that is Phi=90(deg)
so I think myself that Co-polar is the pattern in which the main lobe magnitude is larger so the directivity plot as a function of phi for theta equal 90 degree is the co-polar. and the other plot is the cross polar,correct?

Dude read this,

It will help you a lot.

Directionality is how strong is the gain at that particular point. It depends on type of antenna, such as handphone of course you don want directionality because you want the handphone antenna to receive signals from different directions.

Basically, directionality means your gain intensity. If you see your gain pointing aggresively at one direction, that means the directionality of the antenna is of that direction, but if you don't see any gain pointing anywhere or rather scattered around the region...that means is not a directional type of antenna.

On your second image...

The E-plane is the red color that shaped like a peanut.

The H-plane is the green color omnidirection pattern (omnidirection means that it's circular all around).

Vertical and horizontal planes are defined by the antenna orientation relative to ground. The radiation patterns are taken with this reference. You can turn the antenna by 90 degrees and change its "vertical" characteristics into horizontal, etc.

The "co-polar" means that the particular antenna pattern is measured with a reference antenna having the same polarization. If the antennas, the measured and the reference, have orthogonal polarizations, then the antenna pattern so measured is named "ortho-polar, or cross-polar".

how do you understand wich one is e plane and wich one is h plane?

how do you understand wich one is e plane and wich one is h plane?

Use the hfss and plot the the current density and you will see your current movement, and from there you will know where's your e plane and then the 90 degrees of it will be your h-plane (use left hand thumb rule)
