Thank you. Admin...

Hi Admin,

i was looking for a 2500mhz antenna and i came across with this antenna and just want to verify if my understanding of the measurement is correct

R = 165mm

Patch = 64mm

d1 = 43mm

fp = 9.3mm

space from reflector to patch = 6.5mm

distance from reflector to d1 = 31mm

thanks admin.

Hi. 

 

I have built antenna with latest design. I observed upload speed decreased and download speed increased. What could be the reason for this? Image attached

Can u pls share the details of that latest design?

Hi again Mr. Admin, can I get some help with this file?. Thanks.

So this one is not working?

,,, this antenna is very similar to Olkhon MIMO antenna 2 x 13 dBi (1700-2700 MHz) , but I don't know why it doesn't have such a wide frequency band...!!!!

,,,,,,, anyway, if you want, I'll try to do a simulation for the 1800 MHz frequency...!!!

its broadband antenna.. oh okay..

How to make it . If use double sma port??

if you want mimo for that  just search here i'm sure you'll find one that'll suits your preference..

nice, what frequency this antenna operates?

Try Mimosa..

is the screw metal or plastic?

and is it possible to make this in galvanized steel?

i've been using a non-isolated yagi antenna.. so far no problem..

thank you..

V is 75mm for 2.4Ghz?

this one..

thats for 3G 2100Mhz

how about miniPCIe to usb adapter?

the farthest distance between vibrator and first director I've seen is 9-10mm..

 This difference, increases the bandwidth and increases the distance between directors can increase the gain of the antenna.

which one increases the bandwidth? vibrator?

its okay to solder that part?

what are the dimensions?

,,, the gain is the same but a better focus results...!!!

But, I think the best solution is this...

same dimensions?

wow, this one? 9dbi.. 

hey, i'm just wondering what would be the gain that i made? assuming that the patch placed in the middle.. 

i'm going to redo my work,,.

thanks admin!
