Publication number: 20240113439Abstract: A method for propagating signals with an automatically-tuning antenna uses an ultra-wideband antenna formed from a coaxial cable passed through the center of a conductive tube. The center conductor of the coaxial cable is connected to an end of the conductive tube, and the shield of the coaxial cable is not electrically connected to any conductor. Two ferrite beads are disposed serially on the cable beneath the tube, spaced apart from the tube and spaced apart from one another. A centering spacer maintains the coaxial cable within the center of the tube. An electrical signal is applied to a proximal end of the coaxial tube. The antenna is automatically tuned as the frequency of the electrical signal changes, without a need to reconfigure the physical components of the antenna.Type: ApplicationFiled: December 14, 2023Publication date: April 4, 2024Inventor: Roger Owens
