How many wavelengths diameter are required for this to work?
For example, how big would a lens have to be to work at 902-928 Mhz for LoraWAN?
- jboirazian 2y agoHi mikewarot, As a general rule, Luneburg lenses need to have a diameter at least equal to the wavelength of the frequency they are designed to operate with. Because of this, Luneburg lenses are more cost-effective at higher frequencies, making them particularly suitable for applications in the GHz range. It is possible to develop a Luneburg lens for LoRaWAN, and I am currently working on a DRC check for various wavelengths
