Hello All,

I am building a 2.4 GHz Yagi antenna for a project, its bandwidth must be cover 2.4 to 2.5 GHz.
I have already constructed the antenna and assembled it, what i need help is to properly match it to standard 50 Ohms to ensure maximum efficiency.

What i have gathered so far is that i need to use a balun to match the resistive part and a reactive section to match the reactive part of the impedance.

I am going to purchase a ready made balun for the resistive part leaving me with the reactive part to be matched, please send your opinions, prayers and possible easy solutions to match/cancel the reactive part.

Here are the results from a VNA :

2.40 GHZ: 89+50i Ohms:

2.45 GHZ: 140-26i Ohms:

2.50 GHZ: 58-70i Ohms:


Thank you :)
