[wooyongKim]

hi, i gonna make a single wireless communication between nRF51822 chip and smartphone(nRF Toolbox) .

i can download some refernece layout of nRF51822 chip but there isn't patttern design information of monopole antenna.

can i use the short range (less than 1m)BLE communication without pattern antenna??? just with below schematic??

Well for the small cost of a dongle, DK or EVK you could always cut the trace to the antenna as a quick and dirty experiment to see if the result met your requirements.

We have some white papers here. "nWP008 - λ/4 printed monopole antenna for 2.45 GHz" delves into antenna design. It was written for the legacy nRF24 SoCs, but I guess it should be transferrable to nRF5.
