Microstrip antenna with wide 3dB beamwidth is presented for satellite application. A simple slot is used to achieve circular polarization with the coaxial feed method. Cone structures are used to enhance the 3dB beamwidth. Cone structures are designed with aluminum and copper material. Then the structure dimension is optimized to obtain wider beamwidth. The result shows that the antenna with copper structure obtained a maximum beam width of 187 degrees and 124.4 degrees to the aluminum structure. The antenna design withcopper structure with 133.7 degrees at $phi=0$ degree and 134.9 degrees at phi=90 degree is chosen. Antenna resonated at frequency 2.22 GHz with gain obtained 2.78 dBi.
