PCB antenna or Chip antenna?

[YASH]

Hi All,

This is my first time i am designing a PCB for nrf52840, I need a suggestion regarding the antenna to be used. I am going to have an application over BLE. Which antenna should i use in my design? PCB or Chip ? and what could be the humble guidelines which you would like to suggest me?

Thank you in advance.

Thank you very much for this. Although i have a few more questions since i am new to this. Which configuration should i use in this out of the six? [link text]

(infocenter.nordicsemi.com/.../nRF52840_OPS_v0.5.1.pdf)

turn to page 688 in that link pdf.

i am thinking of connecting batteries of size AA as my power supply.

i want to use a Bluetooth low energy for short range and want to connect an OLED display and an SD card onto it.

Thank you in advance for answering my questions.

That depends on which of the features listed in table 148 that you need, i.e. NFC, USB, the ability to supply external circuits using the internal power supply of the nRF52840 and if you're using the DCDC or not. If you do not plan on using the USB nor the NFC and plan on powering the chip from 3v, then you can use config 6.
