Re: [PSES] Antenna gain measurement standard

[Brent DeWitt]

I forgot to say that, depending on the frequency (higher is worse) it’s almost 
impossible to know what the maximum antenna gain you will find in a full 
spherical is versus three orthogonal cuts.  In my products I’ve seen 7dB 
difference at 5 GHz of an antenna in a product.



It’s also worth noting that there are _very_ few submittals I’ve seen that 
include spherical pattern data.  The three axis palanr measurements are much 
more common.



Sorry for the list pollution of two posts back to back!

Greetings,

Does anyone know which standard is used for measuring antenna gain?

Are 3D antenna gain measurements typically different than 2D with regards to 
peak gain?  If so, what's typical delta, 0.5dB or less?

Re: [PSES] Antenna gain measurement standard

[Brent DeWitt]

Hi Stephen,



Lots of questions are required to answer your question with any accuracy.  I 
assembled a system to do spherical patterning to our product antennas above 1 
GHz, so I have some exposure to the problems.



A few of those questions:

-  Are these product antennas rather than well behaved metrology type 
antennas?

-  Are they independent or built into a product?

-  Is the transmitting device unique or intended to be used as a module 
in many products?

-  What is the frequency range to be investigated?



If I can make a guess, my interpretation of 2D would be planar pattern cuts on 
each of three orthogonal axes vs 3D being an altitude/azimuth pattern measured 
at some spherical radius.



Just to be even less helpful than I have been, there are IEEE, ANSI and IEC 
standards that don’t always agree and need more information to pick and choose 
from.



Keep at it!

Re: [PSES] Antenna gain measurement standard

[Bill Stumpf]

I think perhaps Stephen is referring to the 3-dimensional radiating pattern of 
the antenna, meaning recording all of the antenna radials in the sphere as a 3 
dimensional pattern.  That being said, there should likely only be one radial 
of maximum emission.

I will have to defer to someone who knows what 2D & 3D means, because I don’t. 
I have also not heard of “maximum” gain. Gain is usually defined along the 
radial of maximum emission, and despite most antennas being rather obvious 
which direction that is, the best way is actual measurement.

Perhaps you know this already, but you can visualize radiation as the power 
radiating through an imaginary transparent sphere enclosing the antenna. An 
antenna will usually create a main lobe and many lesser sidelobes. Identifying 
the axis of the main lobe can be time intensive, especially if you have a 
complex antenna structure and no initial idea of how it will perform. The 
antenna gain will be a combination of antenna efficiency and directional gain 
(think of how a flashlight may have internal losses and a very narrow emission 
beamwidth). If you have a high directional gain, the beamwidth may be only a 
half-degree in both the azimuth and altitude axes, and finding the center of 
this invisible beam may take hours of scanning (as you have to scan every 
radial around the sphere). Accurate jigging is a must, followed by methodical 
investigation.

Thanks for the response.
I am looking to measure the gain of an antenna in order to calculate EIRP of a

As far as the 2D vs. 3D, I don't have any values.  I was hoping some one who

[PSES] EMC Compliance for various countries

[Ravinder Ajmani]

Hi Experts,

One of our customers has sent us a list of all the countries, and wants us to 
indicate our product's compliance against each of them.  Our product testing 
specifically covers the following:


*   US and Canada

*   EU

*   Australia / New Zealand

*   Japan

*   Taiwan

*   South Korea

My assumption is that testing to these countries' requirements should 
technically cover the requirements of most , if not all the countries.  However 
some countries may have unique reporting requirements, while others may accept 
the standard report.

I will appreciate your opinions on this.

Thanks a lot.

[PSES] Retirement and subsequent job opening

[Gary McInturff]

I have announced my pending retirement and we are now looking for my 
replacement. I will be here another few months and the hope is to find a 
candidate and have them on board before I leave so that I can get them up to 
speed before leaving. I work with good people and the company supports its 
employees

The particulars are here


  *   External applicants are welcome to apply at 
www.esterline.com/careers, click on the blue 
"Search Openings" rectangle, there are actually two positions one here in Coeur 
d'Alene, and the other in Everett. ( I used to do that one until I moved over 
here)

I can tell you this is a great place to live and work, lots of outdoor 
activities, great place to raise a family, lower cost of living, but big enough 
that there are major entertainment opportunities. A few hour drive to Seattle 
gets you Major league sports - baseball (Seattle Mariners), Football (Seattle 
Seahawks), and Soccer (Seattle Sounders) and then you can leave the mayhem and 
return to Spokane/Coeur d'Alene for stress free living. (My opinion)

Candidates only please, and if you prefer you can send the resume as noted 
above or you can send it to me but please do so privately rather than spamming 
the list

 Greetings,Does anyone know which standard is used for measuring antenna 
gain?Are 3D antenna gain measurements typically different than 2D with regards 
to peak gain?  If so, what's typical delta, 0.5dB or less?
Regards,Stephen
