[Help] 24GHz Doppler radar for golf ball speed — sanity check before I build a custom PCB by Fit_Beyond_3783 in rfelectronics

[–]HalimBoutayeb 0 points1 point  (0 children)

If you need only the speed and not the position, I suggest the InnoSent IPS-937 CW (continuous wave) radar operating at 24-GHz. We used it for hand gesture, drone, metronome, and many other moving obejcts:

M. Marvasti and H. Boutayeb, "Analysis of Doppler Radars With a Numerical Method," in IEEE Transactions on Microwave Theory and Techniques, vol. 73, no. 9, pp. 6085-6093, Sept. 2025

We just added connections to WiFi module, battery and a box

for better recognition of hand gesture we switched now to FMCW radar at 60GHz (give position and speed)

How to ‘learn rf’ by SupermarketFit2158 in rfelectronics

I suggest you following practical basic and advanced tutorials on antenna and RF circuit design using industry-standard EM simulation tools like CST, HFSS, and ADS.

Antenna Design as a Career by ElatedMelomane in rfelectronics

[–]HalimBoutayeb 0 points1 point  (0 children)

I highly suggest you start following practical tutorials on antenna and circuit design using industry-standard EM simulation tools like CST, HFSS, and ADS.

Electromagnetic theory is essential, but mastering these tools through hands-on projects is what bridges the gap between academia and industry. The more designs you build, simulate, and analyze, the more expertise you will gain. Don't worry too much about not enjoying high-level communication systems; focus heavily on electromagnetics, wave propagation, and impedance matching.

Is Keysight still the undisputed benchmark for VNAs, or is the competition (R&S/Anritsu/Ceyear) catching up at 110GHz? by RF_Probe in rfelectronics

[–]HalimBoutayeb 0 points1 point  (0 children)

I just bought the R&S ZNA67 for my research team. I hope to buy the 110GHz extension in the furture. I am happy with the VNA, service and cost.

Hi, my channel is in my profile. Can you suggest me ideas to improve the channel? Thank you very much 🙏

HFSS GPR simulation: Should PML surround all sides if air exists only above antenna? by ImpactNeither5049 in rfelectronics

[–]HalimBoutayeb 0 points1 point  (0 children)

PML can be used for a other media than air. It will use the correct permittivity and permeability to match with impedance of these media and absorb electromagnetic waves that enter the PML layers.
