Cardioid patch

[jomy]

Will say hello to all!
Sorry,I do not know Russian well!
I propose a new idea for a patch antenna!
Watch this site:
http://www.mathcurve.com/courbes2d/c...cardioid.shtml

Cardioid is a curve and I think would go with size a=24mm.
What do you think?!

[mcWit]

This is interesting idea. But I think, that Cardioid is very complicated in manufacturing.

[jomy]

for mcWit,
I am interested in how to conduct a simulated cardioide!
THANKS!

[mcWit]

I have not understood. What goals do You pursue?

[jomy]

If this type of cardioide is better than the circular?!

[mcWit]

I think, I am sure of that, the circular patch is more better then the cardioide.

[jomy]

What you say about this Mister mcWit?

[mcWit]

Chat was not about the antenna pattern.
I thought that You suggested to replace the circular patch with the cardioide in a design of the sector antenna.

Все равно не понятна идея с применением кардиоиды в патче - как ее питать. Нужно делать модель и крутить ее.

All the same the idea with application cardioide in patch isn't clear - as it to feed. It is necessary to do model and to twist it.

To mcWit : The topic should be divided.

[mcWit]

Подождем реакции товарища, если что то разделим.

HELLO EVERYONE!
At first I will present some data for patch constructive cardioid:
watch pictures!





technical data:
DA=163,48mm
DG=122mm
DR~57mm
hr=8,54mm
h>45,14mm
Hch=136,56mm

feed to the point of inflection "0":a=24mm;C(18,31);D(18,-31)

PS.The cardioid pattern can be for almost all types of antennas...I think!!!

A GOOD DAY!!!!!!!!!

Увидел первый рисунок и вспомнил где это я видел http://www.lan23.ru/forum/showpost.p...01&postcount=6 и далее по ссылке http://www.ntpo.com/patents_electronics/electronics_4/electronics_323.shtml

Has seen the first drawing http://www.lan23.ru/forum/showpost.p...01&postcount=6 and has recollected where it I saw and further under the link http://www.ntpo.com/patents_electronics/electronics_4/electronics_323.shtml

I can not understand, why cardioid it is supposed to use?

[jomy]

For this:

[jomy]

And taking into account the GOLDEN SECTION,

must take a=24,67mm
A good day!

[mcWit]

How can you determine other dimensions?
