try to help me

First the element should be right-hand or left-hand circular polarization. Then design the feeding network for the array. You could follow the example in the antenna books or papers.
 

which book?which chapter?may you introduce it me?
plz help me
l need it
 

Microstrip Antenna Design Handbook,Ramesh Garg, Chapter 12.

Antenna Theory: Analysis and Design, Balanis,Chapter 6.

- - - Updated - - -

Antenna Theory and Microstrip Antennas, D.G. Fang, Chapter 3 and 6.

In Chapter 6, there are: 6.3 Design of Power Divider and Transmission on the Transformer.
6.4 Design Example of Microstrip Antenna Arrays
 

Not necessarily only RH or LH. The patch can be dual-linear element with in front a 0-90° hybrids, the two hybrids port can be used for LH an RH Circular Polarization.
