Biquad Antenna

304 posts in this topic

This page details the construction of a biquad antenna. The biquad antenna is easy to build, and provides a reliable 11dBi gain, with a fairly wide beamwidth.

what are you getting 16.4dbi from?

can you post the CST files for this?

Hello there.
Congratulations on your work.
As amateur I do drone drill with FPV systems.
One of the biggest problems with this hobby is the antenna.
I am over biquad antennae.
And I want to make one biquad antenna for 5.8 GHz.
This pcb design was really amazing.
I congratulate you.
Can you make a biquad antenna for 5800 MHz?
I am grateful to you.
If you share the measurements, I can easily build it.
If the PCB thickness is 1mm, it will be lighter.

WELCOME TO THIS FORUM ...!
I'll try to solve your wishes,,,!!!

But I think for 5.8 GHz you can make a panel with 4 biquad antennas, how about ... ??

My dear brother.
I'm really grateful to you for that.
There are some studies I have done, but they are built entirely with theoretical calculations and do not work with the right frekans

An antenna with 4 panels is quite large.

I have built various pcb baklava with theoretical calculations for 5800 MHz.
But I could not catch the right frequency.
For example, the pcb in this picture was measured as baklava 5560 MHz frekanssta 1.03 vswr

I like your design so much but very much.
This design works.
I use RF Explorer Analyzer to measure antennas.
If the design in this picture works, I would definitely like to build and test it at 5800 MHz frekans

The dielectric coefficient of the PCB must be taken into account

What PCB do you have?

frekans =frequency,,,,???

,,, sadece 100x100mm !!!

100x100 mm becomes a very large antenna.
I'm trying to make a bi-quad with 50x50mm panel size.
You can look at the pictures of the sample work I've done.
My handheld antennas were quite successful. But it takes a lot of time. I also have to do more than one experiment to get the right frequency and vswr value.

FR41mm pcb.

Frequency = 5800 MHz
