maximum output power and antenna gain of ZOR 1.6mm antenna design from Dialog Semiconductor's application note AN-B-027

Can we please get the maximum output power and antenna gain of ZOR 1.6mm antenna design from Dialog Semiconductor's application note AN-B-027?

we used the ZOR 1.6mm antenna design from Dialog Semiconductor's application note AN-B-027 and included matching of the PCB trace for 50 ohms. During EMI/EMC testing, the test house is asking for a tune-up information which can be checked out maximum output power and antenna gain as in the example below:

Power and tune up information for MPE-calculations

Max output power:                                        5dBm

Limits for output power deviation:             +/- 2 dB

Antenna gain:                                                  3dBi

The path loss between the chip and the antenna is negligible.

Maximum EIRP:                                              10dBm

(5-2)dBm + 3dBi = 6dBm EIRP

(5+2)dBm + 3dBi = 10dBm EIRP

Hi anushiya,

Hi anushiya,

Please notice that the maximum output power is not relevant here, as it's determined by the BLE chip. The +10 dBm is no problem at all.  Even +20 dBm is fine as well. The antenna peak-gain is around at ~ 0 dBi. Keep in mind that the antenna gain is not constant, it varies over angle and you could check it from the radiation diagram in AN-B-027 document. The antenna gain variation is bigger than the listed limit of +/- 2 dB as you mentioned in your thread.

Thanks, PM_Dialog
