I'm interested in any useful sources/books-papers/code regarding the calculation of antenna patterns at the pressence of nearby obstacles (walls, metallic towers/objects etc). I'm interested in first principles on how to approach the topic. Any help or pointing to the right direction...
I was wondering if anyone knows how to combine (interpolate) 2 antenna pattern cuts (Vertical and horizontal) to a 3D pattern. Any directions to some matlab, c or other code, or relevant links will be much appreciated.
Hi to all,
Can anyone provide some input how one can plot/generate in matlab and/or C# (or C++) a 3D antenna pattern from the E and H plane patterns?
Any input will be highly appreciated.
Many Thanks, Cross
antenna far field calculation program
I was wondering which simulator people would recommend in the following scenario.
Imagine that the problem is the estimation of the near and far field several tenths of meters away from an antenna (near and far field) by considering also the...
Does anybody have any information on developments in satellite receive antennas. Any information on flat plated or alternatives to dishes?
Any information/links/documents will be greatly appreciated
near field calculation
Anybody nows the easiest way (or software) where you can import an antenna pattern or structure and check how much is the received field in the near field region or how this field diminishes in the near-field region with an increasing distance from the antenna? The...
Except everything else that have been mentioned, make sure you don't have a lossy cable connecting your antenna to the first stage (filter or LNA). A look at the Friis Formula will show you what you need to do and why.
This is tricky. You need to take into consideration that the constitutive parameters will change in the 2-10GHz range. Also If the concrete is reinforced this will introduce frequency selective effects.
Does anybody now what is the maximum gain that can be achieved through a patch antenna design having the minimum possible dimensions?
I have seen patch antennas having a gain of 19 dBi (or even 23dBi) at dimensions of 0.37X0.37m (19dBi). Have you seen or do you know if we can achieve an antenna...
Did you have a look in their web page (Minicircuits) or the data sheets. If you are talking about a Minicircuit active mixer the power is required for the internal amplifier module so current consumption will depend on the model. Passive mixers don't require any biasing.
