Can this Antena cause the nRF51 chips to burn?

myjtag

Hi, I have used this antenna for my nRF51 layout, but it seems that the device is using very high currents! like in order of 200mA, I just wanted to know if this is because the antenna is a short circuit at DC or I have done something else wrong!

    OK. Depending on the type of antenna, I agree it could be connected to GND. and not be a electrical short to gnd.

    But perhaps the autorouter PCB package decided to directly connect it to GND.

    I would have thought, best practice would be to show the antenna as an inductor to GND if thats what is physically required, and then create a PCB symbol which is the physical shape of this inductor

    This would get rid of the DRC errors without accidental shorting both ends of C8 directly to GND
