Microstrip antenna design factors affecting the range of antenna
Theres too many things involved.. You might need more gain hence you might have to design an array. Path losses need to be taken into consideration.. I mean theres a lot of stuff..
You'd be better off starting with the frequency of operation and then going from there..

It seems that you only want a receiving antenna. So, the directivity (not the gain) is the most important part for you.
my requirement is to design a transmit/receive antenna for vehicular collision avoidance radar at 24GHz which should detect at a maximum range of 100...what are the fectors i should consider for the design to achieve this range and how should i proceed?
Will the vehicle come in a specified direction or in any direction? If it is the former, you may want an antenna array.
Anyway, I believe that the 100 meter range is not a big concern for your system.
Try to obtain these parameters in consecutive order for starters, before you progress to add other things:
(1) Desired frequency bandwidth
(2) Dimensions constraints
(2) Good impedance matching
(4) Controllable radiation patterns
(5) Desired gain at desired frequencies
(6) Efficiency or directivity
Hope this helps.
