PCB Antenna spiralArchimedean?

Hi is it possible to create an spiralantenna on a PCB?

Like the combination of:

fRin=0.05;

Rout=0.15;

spiralobj = spiralArchimedean('NumArms', 1, 'Turns', 6.25, ...

'InnerRadius', Rin, 'OuterRadius', Rout, 'Tilt', 90, 'TiltAxis', 'Y');

and

patchMicrostripcircular

Because the first is in "the air" (maybe i did not get it right) and with patchMicrostripcircular u "just" have an round copper plate (maybe i also dont get this right)?

Sorry for my english i hope u can help me and thank you.

Hi Lukas,

Based on your query, it seems that you would like to implement a spiral along with a patch antenna. It is possible to have a spiral along with a patch. Please consider the following code.

Rin = 0.05;
Rout = 0.15;
spiralArchimedean('NumArms', 1, 'Turns',6.25,'InnerRadius',Rin,'OuterRadius',Rout,...
    'Tilt', 90, 'TiltAxis', 'Y'); 
cp =  patchMicrostripCircular; 
show(cp)

with regards,

First let me than you for the answer,

But now is cp just a cupperpatch...

I need a patch where the antenna is spiral.

And with spiralArchimedean is it a wired spiral Archimedean lol

and i need a printed circuit board with a spiral Archimedean.

Hi Lukas,

Can you kindly elaborate the requirement. Based on your statement, it seems that the requirement is a patch antenna with a spiral where the spiral part is hollow?

Thanks,

Gokul
