Abstract :
A circularly polarized square MSA with one pair of crank-shaped slit at each edge is proposed for wireless sensor network. The simulated bandwidths of 3dB-axial ratio with 10dB-return loss is 2.398GHz-2.482GHz (3.5%). Moreover, the antenna has the radiation characteristic with wide beam width. The size of the antenna patch is approximately (0.16 wavelength)2. The designed antenna is small in size.
