Flexible antenna with capacative plate coupling
TLDR
A whip antenna as mentioned in this paper is constructed in three sections which screw together end-to-end to form the complete antenna, each section comprises a flexible fiberglass rod which is surrounded by a sleeve of braided copper wire over a major part of its length, this sleeve serving to pass radio frequency current along the section during use of the antenna.Abstract:
A whip antenna is constructed in three sections which screw together end-to-end to form the complete antenna. Each section comprises a flexible fiberglass rod which is surrounded by a sleeve of braided copper wire over a major part of its length, this sleeve serving to pass radio frequency current along the section during use of the antenna. Two of the sections also each provide a capacitor which is connected in the radio frequency path along the antenna. Each of these capacitors is formed by two strips of copper tape which constitute the capacitor electrodes and which lie opposing one another on the surface of the fiberglass rod of the appropriate section.read more
