Embodiments provide single-sided and multi-layered circular polarized, self-contained, compound loop antennas (circular polarized CPL). Embodiments of the CPL antennas produce circular polarized signals by using two electric field radiators physically oriented orthogonal to each other, and by ensuring that the two electric field radiators are positioned such that an electrical delay between the two electric field radiators results in the two electric field radiators emitting their respective electric fields out of phase. Ensuring the proper electrical delay between the two electric field radiators also maintains high efficiency of the antenna and it improves the axial ratio of the antenna.
