I found three antennas in your offer, which I could use in a device with LTE-M communication. SR4L049 SR4L034 and A10340. I wonder which one of these will be the best for my application, because PCB dimension will differ from those one described in antennas datasheets. PCB width will be max 30mm and length - max 120mm (preferably 100-110mm). Could you send me some information how it will affect antennas performance? Device will be utilizing LTE-M frequencies in bands: B1 (2100) , B3 (1800) , B20 (800) and also 868MHz frequency. It will be great if you could recommend any other antenna in your offer, if there is better than these three mentioned above for this PCB dimensions.
