Abstract: A compact wideband single feed circularly polarized antenna is provided. The circularly polarized antenna may include a ground plane. The circularly polarized antenna may include a radiating patch with an embedded ring-shaped slot. The circularly polarized antenna may include a via that shorts a round section of the radiating patch surrounded by the ring-shaped slot to the ground plane. The circularly polarized antenna may include a coaxial feed. The inner conductive material of the coaxial feed may be connected to the radiating patch and the outer conductive material of the coaxial feed may touch the ground plane. The circularly polarized antenna may include a slit-slotted parasitic square patch.
