I'm designing a development board using NRF51822 and I need help to select the appropriate chip antenna.?

Hi Guys,

I'm RF beginner and I'm designing a development board using NRF51822 and I need my board to be small as possible so I decided to use chip antenna but I don't know how to select the appropriate antenna for my case.

So I need help to select the appropriate chip antenna.

For maximum range you really need a length of wire. This should be normally 1/4 wavelength for the frequency your using.

Unless you want to go into slivered wave guides and slotted directional antennas ... but then you would have to learn how to calculate the curl of a 2D vector field.

You see my head is hurting again! In the 70's I assembled a "special" waveguide system to suit a complex custom installation. All done using hand tools/ i was told it was impossible without special jigs, tools etc. However when tested to wave guide system have one of the lowest SWR they had even seen - Just luck I guess.
