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 a radiator portion (800) having a plurality of helically wound radiators (804) extending from one end (832) of the radiator portion to the other end (834) of the radiator portion (800). Each radiator (804) is made up of a set of two or more segments (708, 710). A first segment (708) extends in a helical fashion from the first end (832) of the radiator portion (800) toward the second end (834) of the radiator portion. The second segment (710) extends in a helical fashion from the second end (834) of the radiator portion (800) toward the first end (832) of the radiator portion, wherein a portion of said first radiator segment (708) is in proximity with a portion of said second radiator segment (710) such that said first and second radiator segements (708, 710) are electromagnetically coupled to one another.
