for nrf51822 , from where i can get the geometry, relative placement of the components with respect to each other, and the lengths of the transmission lines. only the values of the components are given in nrf51822 datasheet.

    my question is, is it fine to use two matching circuit one for the chip antena as suggested by manufacturer and one which nordic suggested as shown in fig. and will it work in this way.it is only for testing purpose.

     The PI matching network in the nRF51 DK layout will be equivalent with the matching circuit from the antenna manufacturer. However, you will have to tune the matching circuit, i.e. adjust the values, so I recommend that you post your layout here on devzone for a review,

    my second question is  the chip antenna should be exactly 2.4 GHZ or if it is 2.45 GHZ does it matter.

     Any 2.4GHz chip antenna with 50 Ohm impedance should work.
