11 deg

[Sukesh 0]

I am looking at 11deg 2.45ghz antenna 1x4 array max length of 35cm 

 

Possible? Any metamaterials design based on fr4?

 

Gain not important but beam width important.

Sukesh,I don't understand what you want....!!!!

,,,you want a 4-core sector antenna like this...???

Yes, but want beam width 11deg in small size around 400mm max length and width100mm

[Admin 2769]

What does "11 degrees" mean to you?, is it somehow angular width?

,,,,anyway, you can choose from here...

The one you posted should be closer to 15 degrees Elevation lobe , AZIMUTH...closer to 120...you should check the 2d Plot

I want same performance in 350mm max lengths.

 

That's where I am trying

Maybe this suits you...!!!

Higher the Dielectric constant...the smaller the antenna ...and BIGGER the LOSSES...(unless is Teflon sheet) or Foam...

11 degrees is Elevation (UP and Down)  not Width (Azimuth) on this...and you aren't specifying the Polarization (is it Vertical...?)

Yes only one view 

I have tried smaller antenna with high dk still no help because gap is still I need to maintain

Vertical
