摘要
Technologies are presented for providing circularly polarized antenna topologies based on multiple bent-dipole elements over a ground plane configuration. In some examples, Moxon based cross radiating elements may be fed through a hybrid 90° quadrature coupler. The radiating element may be widened and tapered relative to a standard bent-dipole configuration forming bow tie structures with approximately 90° bends to achieve broadband operation. The tapered branches may be split into two sub-branches and the bend angle increased to further increase bandwidth and gain of the antenna.
