Small Size 2.4 GHz PCB antenna

Hi

I am trying to create component in “Eagle” of Small Size 2.4 GHz PCB antenna (IFA)

used for cc2540 TI,

using http://www.ti.com/lit/an/swra117d/swra117d.pdf for antenna description

the IFA antenna is used for Bluetooth low energy like this board http://www.ti.com/tool/cc2540dk-mini

notice I am also total beginner making total beginner mistakes

attached is what I managed to do until now

few eagle design questions

  • how can I make the component with ground plate, so adding him will auto add ground plate

connected to the IFA

  • how can I make the component with via to the ground plate?

  • added layer 19 unrouted, so it will be the clear area around the IFA (see IFA link), is it correct?

  • I want to progress and make the component with places to insert capacitores and inductors for the balun, so it will be simple to add him to the cc2540. can it be done? can I force in component editor ground plate?

  • can you help me design better antenna package, how it should look like?

few general IFA antenna design questions

  • what are the deimention for the ground plate?

  • is it connected to real ground or just a plate?

  • is the ground plate can be the same ground of other components?

  • what is the size of the via to the ground plate?

  • the “Figure 1: CC2511 USB Dongle” in ANO43 show special size wire connected to the L253

and all the balun components are connected in special order. is it importan? is there some document describing it?

  • the “Figure 1: CC2511 USB Dongle” in ANO43 show special plate connected between the antenna and the balun ( black circle in attached image).

is it the ground plate of the antenna?

is it something else?

thanks
