Hello,
I would like to create a calibration set (open, short, load, through) using a network analyzer and an existing calibration set. The idea is to calibrate the VNA with the existing calibration set. Then, measure my "home made" calibration set with the VNA. The measured data should be...
printed induced emf method
Hello,
The induced EMF method is being treated in Antenna theory written by Balanis and applied to dipoles and mutual coupling between dipoles. Does anyone know if and how this method can be applied to a plate dipole? Does anyone have a good reference?
Thank you...
Hello,
Regarding: CAD of microstrip antennas for wireless applications, Robert A Sainati, Artech House. The book is not for sale anymore at Artech House
The programs are compiled in some basic version 16 bit and do not run on a 64 bit computer. Does anyone Know how to run them on a 64 bit...
Hello,
Is there a distinction between specular and diffuse diffraction as is the case for reflections? How is it quantified mathematically?
Thanks.
Best regards.
Hello,
In **broken link removed**
at pp.49-53 the author talks about fresnel zones. Especially the fresnel zone due to reflections interest me. The author gives 2 equations 2.24 and 2.25 which are a bit foggy to me. These equations quantify the radius and the semi-major axis of the first...
understanding and measuring circular polarization
Hello,
I have a few doubts about measuring circular polarized antennas. One method is measuring the antenna under test (AUT) with a linear polarized reference antenna (RA) in 2 orthogonal planes. That is the RA is rotated 90° and the AUT's...
Hello,
When using lumped elements in a microstrip circuit simulation in microwave office, what is the reference plane of the connection? Is it the end of the component or does it have to do anything with the component footprint?
Best regards.
Hello,
I am looking for a broadband (30%) 3-way splitter design with 120° sequential phase output (0°/120°/240°) in equal power. Preferably a microstrip implementation with or without lumped elements or any other off the shelve components.
Thank you very much.
Best regards.
Re: cst in batch mode
hello,
why don't you use the "job control" provided with your cst installation? this works fine for me and it's a lot easier than batch mode.
best regards
hello,
you can work towards the phd degree while working in the industry. it only takes a university promoter, and something to kill the pain :D of working long hours :cry:. beer works just fine.
greetz
Hello,
I am in search for the electrical properties (permittivity and permeability) at L-band of several materials such as, but not limited to:
-various soil constitutions and humidity
-construction materials (glass, concrete, reinforced concrete...)
-natural obstacles such as trees
Does...
This article " The basics of patch antennas" on rfglobalnet outlines the basics. It should get you started.

Re: [CST MWS] ""farfield is inaccurate!!" mea
that's because the simulation boundary is to close to the dipole with respect to the wavelength. it is better to use the open + add space boundary when simulating antennas in free space. cst will set a proper simulation boundary for you
best regards
Re: Final Year Project: Dual-Frequency Microstrip Patch Ante
any decent book about microstrip antennas should give a few examples
more specific books are:
broadband microstrip antennas, Girish Kumar et al., artech house
Compact and Broadband Microstrip Antennas, Kin-lu Wong, Wiley
best regards
Re: Final Year Project: Dual-Frequency Microstrip Patch Ante
hello
it's a lot easier to design small band antennas than broadband antennas. 200 MHz at 10 GHz would be 2 % bandwidth, that's small band. dual band structures are usually built by exciting 2 modes. the natural modes are usually at...
