Simple Patch Antenna

[Admin 2578]

Bottom of a circular metal box can build a simple antenna with an elliptical radiator...

 And this patch antenna with  a parasitic director placed in a conical reflector...

 

[Admin 2578]

Even the best omnidirectional receiver antenna can't match a good directional for range and bounced signal rejection. This right-hand circularly polarized (RHCP) directional 5.66GHz antenna has a forward gain of ~9dBi, a beamwidth of 60 degrees and superb front to back reception ratio . It is easy to point in the general direction of the transmitter and reduces multipathing reflected signals from the rear and sides.

hi teacher jomy   please give me  the mesurement of  patch ellip   antenna  with conical reflector  it looks  interessting .

[Admin 2578]

,,,,dimensions of the truncated-cone reflector :D=136mm , d=40mm, H=27mm

This is very nice for me I have too many parts now not enough antenna. Could I please have the dimensions for this one? Will adding more elements increase dbi?

The distance between reflector and vibrator, and between vibrator and director? I just want to stick a bester on it and do a test.

wait ,,,!!!

I'll do a simulation with the Bester antenna...!!

[Samsterino2.4 2]

Did you ever finish the simulation for this boss?

,,,okay,I will try it today...!!!

@Admin  today is the day Admin. We shall conquer it! are you going to do circular patch or square patch bester simulation?  I think it would be interesting to see square. Also I've been looking around a lot lately. What would you recommend for a 5ghz "ShotGun" sectorial type antenna for high reception ( so wide bandwith i suppose. What's your favorite for picking up faint ap's? Have you seen anything lately new?

,,,hi buddy,where have you been until now...???

,,,right now I'm trying to satisfy your wishes...!!!
