A Simple Patch Antenna

[pragata.my.id 25]

from the beginning of its production, mikrotik focus on network management, not in the wireless world,

"Internal antenna mikrotik indeed several times discussed in forums because the design is less stable."

[Admin 2545]

so you want it?

 

[pragata.my.id 25]

 as I suspected.

the design is definitely bad.

,,,yes, the VSWR it"s bad...!!!!

,,, but isolation between ports and impedances is good !!! !!!

do you think it is worth using or not?

[Admin 2545]

the antenna geometry must be chosen with vswr <1.5

[acri 24]

what is polarization?
vertical or horisontal?

[Admin 2545]

what do you say it is ...?

This patch antenna are cheap in cost, having low profile, and easy to fabricate. Patch antenna have three parts−patch, director and ground.for which it covers the entire frequency range for 2.4GHz

[bejonet 58]

good,,, is very good.. how about beamwidth for this antenna

[Admin 2545]

,,, beamwidth=2412-2484MHz

[bejonet 58]

  no, i mean beamwidth degree and what polarization for this antenna

i change plastic bolt with metal bolt, it can increase the signal, good...

[Admin 2545]

,,,horizontal polarization...!!!
,,,it's good that you changed the insulating spacers...!!!
,,,I will soon present beamwidth degree...!!!

[bejonet 58]

with 2 patch??... it is possible??

[Admin 2545]

"Yes, it can, but a simulation needs to be done .with an impedance adjustment line..!!!

[bejonet 58]

ok,, waiting for simulation please,,,, i can not do it because not have in my old computer and not know how to working with simulation program,, 

 

[Admin 2545]

,,,what kind of computer do you have...???

,,,if you want I can teach you how to work with the antenna simulation program...!!!

[bejonet 58]

yes,, i want to learn how to work with antenna simulation program, please,,,

but this is my computer...

[Admin 2545]

"Yes, the computer is pretty good ... !!!
"why do not you try to look at this forum about the CST program...!!!

[Admin 2545]

,,, something like that ... !?

 

[bejonet 58]

how about this ?

[Admin 2545]

Yes, only if you can do this...

 

[bejonet 58]

which one i must solder and not to soldered, can you give more detail

[bejonet 58]

Yes, i found stacking with coax cable on qsl.net
