This paper introduces an ultra-wideband circularly polarized (CP) asymmetric-S antenna with wide axial ratio beamwidth (ARBW) for C-band applications. The proposed antenna is realized by bending a linearly polarized dipole into asymmetric-S shape with variable trace width. which achieves CP radiation. Unlike the reported symmetric-S antenna. https://parisnaturalfoodes.shop/product-category/tea-tree/
