A circularly polarized antenna with patches on the top is studied in this paper. The antenna is composed of two printed dipoles and four radiation patches which are loaded on top of the dipoles. The antenna is fed by microstrip balum in the middle of dielectric slab. And the balum is connected to a Wilkinson power divider which owns 90 degree phase shift. Numerical simulations of proposed antenna are performed using the 3D electromagnetic simulation software HFSS. The experimental studies of the antenna are also carried out. Measured results show that the parameter S11 is less than -10 dB from 1.1GHz to 1.8GHz while the 3dB axial ratio bandwidth is from 1.27 GHz to 1.62 GHz. The highest gain of 5dBi can be achieved during the operating frequencies.
