Wireless application can work better if the supporting component especially the antenna can transmit and receive the power with low losses due to the misalignment. Reducing the power losses caused by misalignment can be performed with the circularly polarized antenna. The authors proposed the circularly polarized antenna, with 40mm x 40 mm in dimension and FR-4 substrate with the dielectric constant of 4.4. The microstrip line fed and the power divider method were used to get orthogonal mode. From the measurement result, the antenna can work at frequency range of 1.9 up to 2.5GHz omnidirectionally and has an axial ratio value below 3dB.
