X Band Planar Antenna Design Source?
X Band Planar Antenna Design Source?
(OP)
I am a M.E. but my company is looking to outsource the design for a 9.2GHz planar array antenna.
We can make the antenna, we are just looking for someone to do the design. Does anybody have a source?
Obviously there are alot more details but we are just looking for a place to start.
I contacted a couple of Universities but there response was lacking and the price was insane.
Thanks.

I was hoping somebody with the right software could design the channels and slots and centerfeed and we could make the antenna in our shop.
$50,000 is more than we wanted to put into it.
I would love to find a grad student that would take it on as a design project.

That's a fairly large array, approx. 10 inches tall (12 elements) and 30 inches wide (36 elements). 432 elements is a pretty large power divider. The antenna element design is fairly simple, simple patch antenna. The power divider takes much more effort.
You didn't mention the
1) gain, if critical (sets loss in power divider)
2) polarization of the antenna, V, H, Circular.
3) environmental, rain, snow, ice formation factors(affects radome, affects antenna maybe).
In order of time and effort, easiest is the antenna element. Hardest is the power divider.
Depending on how you want to make this, you could make it a two job effort to save money. The full job is probably a $50 price and the two part job may end up a $10K job if you do all the mechanical.
1) Antenna design and
2) power divider design.
Low sidelobe levels may require the power divider to be on the far side of your groundplane so it doesn't radiate (if your -30 dB sidelobe level is critical).

I think boat radars are 9.4 ghz band.
I have a boat radar antenna, 22"x3" X band printed circuit microstrip array (3x24 elements)9.4 ghz band. I has sidelobe tapering on it via the power dividers.
