COUPLED MULTI-SEGMENT HELICAL ANTENNA |
摘要 |
A coupled multi-segment helical antenna is provided having a length that is shorter than otherwise obtainable for a conventional half-wavelength antenna. The coupled multi-segment helical antenna includes radiator portion having a plurality of helically wound radiators extending from one end of the radiator portion to the other end of the radiator portion. Each radiator is made up of a set of two or more segments. A first segment extends in a helical fashion from the first end of the radiator portion toward the second end of the radiator portion. The second segment extends in a helical fashion from the second end of the radiator portion toward the first end of the radiator portion, wherein a portion of the first radiator segment is in proximity with a portion of the second radiator segment such that the first and second radiator segments are electromagnetically coupled to one another. |
