Abstract:

A detailed study has been made of the broadband characteristics of a balunfed, open-sleeve dipole mounted in front of a metallic reflector. VSWR and pattern measurements were performed in the UHF band for a variety of dipole- sleeve arrangements. Multiple cylindrical-rod sleeves and flat sleeves of disc and Greek-cross shapes were experimentally evaluated. Gain data were obtained on a crossed dipole with a tick-tack-toe sleeve configuration. It is shown that, with a proper choice of sleeve parameters, the dipole can be operated over a bandwidth of over an octave with a voltage standing wave ratio VSWR of less than 21.
