Biquad Antenna

[KSM 11]

I made this anthenna and want to make it in PCB. 

[Admin 2685]

Forget about PCB, it's not good...!!!

[KSM 11]

Why? Because it is difficult to make it from a printed circuit board?

[Admin 2685]

,,,no,PCB has poor results...!!!

What if I build it using 1 mm M1/M2 copper?

Yes, it's fine, the thickness of the material doesn't matter.

,,,but what is "M1/M2"...???

Copper comes in different grades: M00, M0, M1, M2 and M3. The grade is determined by the purity of the copper content. M1p, M2p and M3p copper contain 0.01% oxygen and 0.04% phosphorus. Copper grades M1, M2 and M3 contain 0.05–0.08% oxygen.

Brass might be better not so easy to oxidize...or protected from moisture PURE COPPER...(aluminum, zinc,etc)

You'll have bigger losses on DIELECTRICS than metal every time

Dual Port Biquad, correct and suggestions please

Biquad.cst

[Admin 2685]

It's not good, what do you want to do..?

[papagayor 10]

Two ports for a TP-Link MR-100 router outdoor antenna, it has 2 sma antennas, and I want to replace them for better signal gain, as the router cannot fitted outside, because need protection from rain.

I made a biquad in antenna-magus, exported to CST, and then doubled the elements making also a larger reflector.

Biquad.cst

it is better to make 2 separated biquad antennas with individual reflector each

they gonna work better

and with 2 separate you can experiment with -45 +45 polarization etc

[Admin 2685]

I think this construction is better..!!!

[papagayor 10]

For this construction and calculating dimensions for 2.44Ghz biquad, should the 2 sma's be isolated mount on reflector?

[papagayor 10]

Or is better to go on this?

[papagayor 10]

I'll try to draw and simulate both of them on CST

[Admin 2685]

papagayor,try not to post multiple times...!!!!

[papagayor 10]

Also, I'm trying to simulate a Kathrein antenna element for 3.5Ghz, but results on CST look very bad, I like this Kathrein design and if anybody wants to try making some corrections on this it would be a good antenna to use as dish feeder

@Admin Could you help me with the simulation of this antenna, please?

[Admin 2685]

KSM...from where did you get it...???
