I am interested to know what effect will adding a sma plug into the simulation do. Will it make a hugh difference or not. we simulated a antenna with hfss but when we did the anachoic chamber test the results were off a little and the s11 was also off. I have the SMA up through the bottom...
acceptable s11 for antennas
hey guys thanks alot you have cleared alot up for me.
I am using a patch array of 8 strip lines,
I have been trying to impedance match it using the ansoft designer SV program. But i am not having to much luck with that what i have done is got the impedance value...
wouldnt you be better of getting ansoft designer you can download the student version online and there is lots of tutorials on this webpage for that just look
Added after 3 minutes:
here is a link
lots of information on there about designer
i have designed a patch antenna with a gain of 16db but only a maximum of -8db s11 for the frequencies i want. will this antenna be able to still transmit or do i have to get the s11 lower? i have heard that max should be -10db for the s11. i only want it to go max 100m
How would you go about making a quasi yagi directional is it simply a matter of increasing the number of directors at the distance relative to a normal yagi?
if i use this
and than add more directors at a 1/2...
I am trying to create a directional antenna by using a simple patch antenna and a parabolic dish. i understand about having to guess the possition between the focal point and the dish but i was wondering what is the best for reflection what type of material. currently i can only get it down to...
