Abstract:
1. An antenna feed configured to receive a signal having a wavelength, comprising: a cylindrical body; a first pin group including a first pin extending across the center of the cylindrical body at a first angle, and a second pin extending across the center of the cylindrical body at an angle rotated approximately 22.5° from the angle of the first pin, wherein the first and second pins of the first pin group are spaced in close proximity; a second pin group including a third pin extending across the center of the cylindrical body at an angle approximately equal to the angle of the second pin of the first pin group, and a fourth pin extending across the center of the cylindrical body at an angle rotated approximately 22.5° from the angle of the third pin, wherein the third and fourth pins of the second pin group are spaced in close proximity, and wherein the second pin group is spaced approximately one quarter of the wavelength away from the first pin group; a third pin group including a fifth pin extending across the center of the cylindrical body at an angle approximately equal to the angle of the fourth pin of the second pin group, and a sixth pin extending across the center of the cylindrical body at an angle rotated approximately 22.5° from the angle of the fifth pin, wherein the fifth and sixth pins of the third pin group are spaced in close proximity, and wherein the third pin group is spaced approximately one quarter of the wavelength away from the second pin group; and a fourth pin group including a seventh pin extending across the center of the cylindrical body at an angle approximately equal to the angle of the sixth pin of the third pin group, and an eighth pin extending across the center of the cylindrical body at an angle rotated approximately 22.5° from the angle of the seventh pin, wherein the seventh and eighth pins of the fourth pin group are spaced in close proximity, and wherein the fourth pin group is spaced approximately one quarter of the wavelength away from the third pin group.
