Claim Text:
1. A micro wideband antenna feeder, comprising: a quad scheme antenna irradiating a first current distribution, the quad scheme antenna being any one of a quadrifilar helix antenna, a quadruple inverted F antenna, and a quadrifilar spiral antenna; and a cross dipole antenna installed in a cross shape in the quad scheme antenna, the cross dipole antenna irradiating a second current distribution orthogonal to the first current distribution, a transmission circuit substrate coupled to the quad scheme antenna or the cross dipole antenna; and a reception circuit substrate coupled to the quad scheme antenna or the cross dipole antenna, wherein the quad scheme antenna or the cross dipole antenna shares same transmission/reception focus and space as an assembled parabola dish, and wherein a frequency generated from the cross dipole antenna installed in the cross shape in the quad scheme antenna has a frequency band higher than a frequency generated externally from the quad scheme antenna, and both transmission and reception bands meet wideband circularly polarized characteristics.
