Dual‐Loop Antennas With a Branched Feed‐Line for Broadband Circular Polarisation
Electronics Letters, Volume 61, Issue 1, January/December 2025.Using the method of moments, we first analyse reference and present dual‐loop antennas with a perturbation segment and branched feedline, respectively. The loop elements of each antenna are gradually rotated for an increased 3 dB axial ratio bandwidth.
