Hamza,I don't think it's the best solution...!!! ,,,see this...

,,,the best...Batwing 5,5 GHz...!!!

DavidER, ,,,this Bester antenna it's only for 50 Ohm for 75 Ohm need other sizes for feeding...!!!

It can be with an antenna of this kind...

,,,maybe something like this will help you...https://www.freemansgarage.com/index.php/2010/02/01/long-range-wifi-long-range-internet/

,,,no, it doesn't depend on the material...!!! ,,,but the most important thing is that the vibrating disc should be made of weldable material...!!!

,,,another variant of Bester antenna with 5 elements by Alexander Bars author.... ,,,by...

,,,this is almost real... ,,,and these dimensions are updated...

,,,yes, it seems that this antenna works, but it is still narrowband...

,,,this it"s okay...???

,,okay, I will try...!!! I use cst.

,,,hi buddy...!!! ,,,install version 2024...!!!

,,, yes, it is possible, but with other dimensions...!!!

I don't have the file but in the future I will be able to give you the dimensions.

27 dB, MIMO, for router and modem 5G (N78), LTE (1800, 2100, 2300, 2600), Wi-Fi 2400 Frequency range: 1700 to 4200 MHz

COMPARISON BETWEEN CIRCULAR AND RECTANGULAR DESIGN OF YAGI PATCH ANTENNA Following table2 gives comparison of results of Rectangular and Circular patch antenna: From simulation result of circular and rectangular yagi patch antenna it is clear that the performance parameter changes as change in geometry. COMPARISON OF SIMULATION ON DIFFERENT SOFTWARE Following table gives comparison of result on different software: From above table it is clear that performance of antenna parameter vary with simulation software .HFSS gives the improved results. CONCLUSION In previous work same antenna was designed in CST MICROWAVE studio software but the result were not satisfactory. Same design in HFSS gives improved result. With this design we get improved result of return loss ,F/B ratio, but gain result is not satisfactory. Gain can be improved by changing some dimension. For wifi antenna is the best solution previous work has done with CST software , but some antenna is proposed with HFSS software which has given the improved result and lower F/B ratio. Dielectric constant used for this antenna is FR4 epoxy which is easily available in market. By changing the shape, dimension the simulation will be performed and the result will be taken and with best result antenna will be fabricated.

,,, two cables at 120 degrees can also be used...!!!

I think you can try a Bester antenna from this post.

,,,to make the simulation easier, you can leave air space...!!!

,,,anyway, this is quite small... 150x230mm

,,,it's your job, do as you want..!!!

,,, yes, the frequency band can be extended, but it's extra work...!!!

I don't have the file anymore, but there are drawings on this post...!!!
