A small, relatively wide-bandwidth, active antenna is usable in a wide range of applications spanning the VLF and SHF bands. The antenna is capable of receiving relatively weak radio frequency signals having a signal strength below that detectable using conventional passive antennas. The antenna includes a lumped constant element forming an electric wave receiving part, and a high impedence amplifier having input terminals connected via leads having a short electrical wavelength at the design frequency, to corresponding ends of the lumped constant element. Output terminals of the antenna are connected to a receiver to provide a small, high sensitivity, active antenna.
