    Cardioid patch

    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?!

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

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

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

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

                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.

                      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?

                            And taking into account the GOLDEN SECTION,

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

                              How can you determine other dimensions?
