Admin, 

Please can you simulate this antenna on a 90cm dish if possible?

Greetings  JOMY   very excellent job. i m so curious to know the level of isolation of 2 ports (crossports)  in your antenna design.  being so busy i will post the dimensions as you asked

,,,,and where is the feed point located...???

,,, these would be the results with feeding points at 90 degrees...

,,,it seems that the isolation between the ports is quite good...

i love your work  my  friend   its  writen  in blue   the feed point  34 mm  from the  center  the antenna  is  made for 75 ohm

Two ports are well isolated because two orthogonal modes are being exited with this configuration. Bandwidth at S11 -10dB is reduced.

Bonjour Admin

- est ce que on peut avoir les dimensions pour la fréquence de 1800 Mhz et le résultat d'une simulation?!

- aussi  quel serait le débit pour cette la fréquence de 1800mhz.

merci bien

Bonjour Administrateur 

je vous remercie pour vos  propositions  schématiques .

1- A la lecture du premier schéma, je vois qu'il y a une coupe de 90/72, la coupe de 72 est elle nécessaire ?

2- chez nous , nous ne disposons pas d'un câble coaxial de 50Ohm , le seul disponible sur le marche est le 75 Ohm

3- est t'il possible de rajouter un deuxième feed point 2 (alimentation), si c'est oui(possible) , bien sûr s'il y a gain supplémentaire.

4-  je souhaite avoir les autres dimensions des autres trois autres structure données .

merci bien

1. oui, c'est nécessaire,
2. Je travaille uniquement avec des impédances de 50 Ohm, mais c'est également possible pour du câble de 75 Ohm avec d'autres dimensions de l'antenne.
3. oui, c'est possible.
4. dès que possible.

Bonjour 

malheureument, les câbles de 50 Ohm ne sont disponible sur notre marché, Pouvez-vous ajuster la taille de l'antenne pour qu'elle convienne à un câble coaxial de 75 ohms avec deux (02) feed (deux point d'alimentation ).
