Abstract :
A circularly polarized antenna with low cost foam substrate and film is proposed to obtain wide bandwidth and high performance. The proposed antenna is composed of stacked corner-truncated patches with sequential rotation feed. Having above 20% return loss and axial ratio bandwidths, the designed antenna can be used for application of a broadband system using circular polarization. And, as low cost foam and film is used for the substrate, a low cost antenna can be designed.
