The formula looks alright, but please note that in the formula theta is the angle between the beam peak and the line where your elements are placed on. If your theta is relative to braodside (normal t ...

Hi,

I am performing some simulations in CST in which I need the radiation patterns of a 2x1 array of CP patches pointing at certain angles.
The formula that defines the progressive phase differenc ...

Hi,

I am calculating the field regions and for that purpose I need D (the maximum distance of my antenna). In my case I have this array:

If you use the size of each element (D), then at that distance you would be in the far field for each element individually. WHat I mean is, if you are at a point x, where the minimum distance to the ...

It is known that the conditions needed to be in the far-field region are:

d > 2D^2/lambda

d > 5D

d > 1.6*lambda

Being D = the largest physical linear dimension of the antenna.

PostForum: Questions Related to Antenna Theory   Posted: Thu Dec 03, 2015 12:33 pm   Subject: Received Power in a 2x2 planar array
Hi everyone,

I have one question which confuse me a lot. Here I go:

Let's consider an ideal isotropic antenna which radiates 10dBm (Ptx0 = 5dBm; Gtx = 5dB) and taking into account path losses at ...
