An Ultra-Wideband Circularly Polarized Asymmetric- $S$ Antenna With Enhanced Bandwidth and Beamwidth Performance
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 Input Shaft by bending a linearly polarized dipole into asymmetric-S shape with variable trace width, which achieves CP radiation.Unlike the reported symmetric-S anten
