Antenna for Ultrawideband Channel Sounding [PDF]
IEEE Antennas and Wireless Propagation Letters, 2017 A novel compact antenna for ultrawideband channel sounding is presented. The antenna is composed of a symmetrical biconical antenna modified by adding a cylinder and a ring to each cone. A feeding coaxial cable is employed during the simulations in order to evaluate and reduce its impact on the antenna performance.
