The Extended Gain Hypole Antenna: An Application of Computer Modeling to Antenna Design.
Abstract
The Hypole is an experimentally developed hybrid dipole antenna for use in land mobile and shipboard communication systems. It employs a unique feed system to provide isolation from the degrading effects of a limited ground plane. This results in an increase in performance over an end-fed half-wave dipole similarly employed. Since the Hypole acts as a half-wave dipole isolated from ground, the possibility of improving its performance by the addition of a second properly phase half-wavelength element exists. A design approach using a thin wire antenna computer program was selected over the more tedious trial-and-error procedures on an experimental development. The validity of a computer model of the Hypole antenna was verified experimentally. This model served as the basis for designing the extended gain Hypole antenna, which when built provided a 2.7 db gain over the Hypole. This study demonstrates the successful application of the computer modeling approach to antenna design. (Author)
