Antennas for Drones

,,,it is easier to solder a coaxial cable to the feed point...!!!

I made the Pagoda antenna from the dfx file, I'll give it to you in the article. But it doesn't work correctly. Where did I make a mistake or is it impossible to do it on FR4

I think you should put an SMA connector instead of the discrete port - that might be the mistake....!!!

Can you help install them correctly?

Hello Guys!

I have a problem with Pagoda3b antenna for 5.5GHz. 

As you know Pagoda antenna is an open source project of Maarten Baert. He has got a page with dxf and gerber files of it. 

https://www.maartenbaert.be/quadcopters/antennas/pagoda-antenna/

I've tried to design this antenna for 5.5GHz using dxf files, but central frequency is 5.7GHz

What i'm doing wrong? Help please!!!

CST file of my design:

different solver and different settings would give different F resonance . BUT dielectrics play the BIGGEST ROLE...try higher dielectric constant  WHAT THICKNESSES ? METAL moves fr UP

ussually is 0.035 mm copper 1.53mm FR4

My design is based on Maarten Baert's recommendations. fr4 1.mm (loss free) and 0.035mm copper (loss free)...

coax specs might be off

May be!  I will try to contact Maarten...

FR4 EATS 5ghz energy 

PES and copper tape would be MORE EFFICIENT .

ALL METAL even better
