Re: Antenna should be Single-sided or double-sided?
Well.. with double sided the thickness between radiator and GND will matter a lot.. this helps in bandwidth enhancement.. the advantage of single sided is ease of fabrication especially for flexible substrates, it will help you avoid the...
Have you first done with simulated results? did you use voxel data, phantoms? you have to consider which part of the body you want to test your antenna with.. you can find body tissue properties in the official website of FCC in case you want to build your phantom in your software
I press on what jeeudr said "Does it have any extensions/slots or other modifications ?"
make sure of that first, then go for justifications of your results
same.. printed like PCB, which means it has a very small height (thickness) in "micros" and micro is the very term of microstrip antenna.. in books some use printed and others use microstrip and when you see the contents, they tell you they could be the same..now, many researchers use the term...
you can start with any basic designs like rectangular, circular, square etc.. then apply techniques like notch, bevelling, slots, steps (stairs) to enhance or expand your bandwidth.. also note how important is your ground in enhancing the overall bandwidth.
as long as you can get a good...
Hi everyone,
I'll be glad if can provide me with documented materials about "off center fed microstrip antennas".. Theory and preferably about the mechanism, what things have to do with impedance ..I've come across some researches, but they seemed to implement the way with no much theory...
Hi there,
well, the antenna is considered to be UWB when it has minimum 25% of bandwidth within the range released by FCC
calculate it from here
BW = [f (higher) -f (lower)]/ f (centre)
f centre = [f (higher) +f (lower)]/2
hope this helps
Hi everyone,
I have obtained SAR results from CST MWS, and now I'm confused about the selection of the values that have been calculated.
I wonder which one to take, is it
Total SAR (rms) [W/kg]
or
Max SAR (rms,10g) [W/kg]
Thanks a lot
Wad
Hi everyone,
Anyway, I'm just a beginner in CST and your help will be appreciated. I just designed an UWB antenna in CST MWS, the antenna is : microstrip rectangular patch, partially grounded substrate. BACKGROUND MATERIALS set to NORMAL, Waveguide PORT was designed accordingly. Now, here's my...
