Abstract
A wideband antenna, including a radio-frequency connector providing a radio-frequency current, an elongate radiating element galvanically connected to the radio-frequency connector, the elongate radiating element forming a galvanic radio-frequency current path for the radio-frequency current and at least one generally cylindrical conductive element enclosing at least a portion of the elongate radiating element and forming a capacitive radio-frequency current path for the radio-frequency current.
Claims28
A wideband antenna comprising:
- a radio-frequency connector providing a radio-frequency current;
