Build yagi antenna wifi antenna10/29/2023 ![]() ![]() Its entirely possible that the addition of directors to your biquad in the appropriate polarization will give you an antenna with a lot more gain, if that's what you want, it also solves your matching problem as nothing could be easier than bending the wire to the right shape. However, here is the thing, if the two sides are going out on the sides, you feed the biquad in the middle and its a vertically polarized - not a horizontally polarized antenna. In fact, you might be able to use a biquad element as your driven element for this antenna. Basically the driven element is a piece of wire bent into two squares and fed in the middle. (i use approximately 1 mm copper wire thats used in most of the house wiring here now. A biquad is very simple, as long as you get the measurements and use the right kind of wire. I still have one of them and I went back recently to see how well it resonated since now I have a vector network analyzer. ![]() In the distant past (back when I speht a lot of time in nearby cafes and needed to use my home Internet connection, as I did not want to pay for theirs) I made several biquad antennas based on designs I found on the web. I would ditch the Yagi and make a biquad antenna instead.
