Panel antenna with elliptical patch

[Admin 2421]

This type of antenna was developed by the "sgser" user...http://www.lan23.ru/forum/showthread.php?t=9279&page=49

The panel shows the elliptical vibratory elements which are fed by copper wire lines through a metal plate polyhedra...

 Great achievement by sgser-user ...on 3G(1850-2200MHz)

A variant with polyhedral patches

 

 

 

 

[Admin 2421]

And a simple patches variant

The patches are positioned by means of spacers of polystyrene foam

Where can I install four M6 bolts for mounting the antenna so that the bolt caps do not affect its operation? As here.

,,, to the center, where else ...  !!! ???

[vars-cat 12]

I thought the bolt caps near the wire might have a negative effect. Now I need to get a drawing of the fastener somewhere.

Jomy, can you simulate this antenna with vertical sides and a 2 mm thick polyethylene cover?

,,,okay,I'll try...!!!

,,, this antenna is after an older presentation of mine on some sites...

[Admin 2421]

This boy is wrong...

 

,,, and how it affects the dielectric screen...

jX curve is heaviliy dependent on port design - diameter and length of feed pin wire + size of lip-capacitor  at port

Jomy has SWR=1.41 @ 2.13 GHz, my model has SWR50=1.44 @ 2.13 GHz

if you are going to dramatically change feed port design - you need to optimize port capacitance. -j 20 ... -j 60 is too much capacitance (remove or decrease improvised capacitor)

Request for this antenna was direct TV cable mount (via F-screw soldered to reflector)

P.S. do 75 Ohm SMA exist?

...Try using the 75 Ohm F-connector,,,

 I managed to determine the optimal dimensions for this antenna with dielectric cover plate, but I will not post them....!!!!

,, and I will try to optimize this mine antenna for broadband ....!!!

,,,..!!Judging by the screenshot, you just increased the sides,,,...!! 

I wonder what will happen if you connect two pairs of ellipses in the reflector with such sides? 17+ dBi?

Would you please tell me how to post a question. I can get to this screeen on a new post but no further. I dont see any button that says post. What am I missing?
Thanks you

I do not understand your question ... !!
,,,maybe so..."Drag files here to attach, or choose files..."
