I think this video is really underappreciated. I built this antenna following all the details and I obtained a very good antenna. I even measured it with a NanoVNA and it is spot on channel 3. It was one of the easiest 2.4GHz antennas I've built. I must admit that the only question I have is regarding the length of the inset feedline. Why is that 15.6mm long? I know that is twice the 7.8mm, but why?

How do you think the performance of this build would change if instead of the square panels, each panel wrapped around onto itself so there was an inner ring and outter ring but fed the ssme way.

Hi Andrew - I like this design, there is something very pleasing about its simplicity. If you were to array 4 of these in a row, would the pitch be about the same as the width? I am thinking to make a corporate feed on microstrip, on a 2 layer FR4 PCB, and the air patch elements would be mounted on the ground plane side, fed thru vias. What do you think?

I tend to see a patch antenna as a glorified capacitor. If I measure the VSWR, you'd think it would higher than 1:1 due to this capacitance, but it's not. So I'm a bit confused.
@stevefox37633 жыл бұрын
What sort or gain does it have and how do you determine vertical or horizontal polarisation when its square and symmetrical, I'd like to try one for FPV and it looks more compact than a 2.4ghz double bi quad, how do the two compare? I'm looking for the most directional and high gain on 2.4ghz for FPV.

Can you make video going more detail about feed taps, and is there some formula what those lengths should be? Also how to make defective ground structure. Does the spot and shape of those make much difference? I tried to find info about them, but most research papers. Only cover other dimensions, but not the feed tap gap and DGS.

Hi Andrew, the online calculator doesn’t mention the coax connection strip. The length, width or the amount to cut in. I wish to make an antenna for 1278MHz. .
@andrewmcneil3 жыл бұрын
No it doesn’t the design of the strip feed is a whole other area of RF. That’s why in the video I say that starting with 1/8 wavelength is a good place to start.

@@cosmefulanito5933 It's a network analyzer to be more precise. By the looks of it a scalar version (atleast like he uses it). However, a setup video would still be pretty interesting. Especially since a network analyzer needs to be calibrated for each measurement with known open, short and load standards.
