well actually i need a very very basic wireless communication system so i can use to demonstrate the antennas i have built, so basically i need a transmitter and receiver that use the 2.4 GHz frequency
 
In order to get about 6db gain from the antenna, it would need 8 sectors, with a 1/4 wave section at the top and a fly-lead with N-connector at the bottom. It should take about 2-3 hours to build an antenna using this design, but don't worry if it takes longer, you will get quicker, especially as you only need to make the jig once.

I'd get some cheap standard size Bluetooth USB modules and fit antenna pigtails.
(The 1.5 - 2" long style, not the tiny in-connector ones).

The standard modules have an on-board antenna at the end, it's easy to cut off and solder some miniature coaxial cable in it's place.

The basic 10mW modules are quite short range, you should be able to demonstrate the range change with different antennas fairly easily.
