Antenna, Wide-Band

an antenna characterized by the fact that its performance factors (radiation pattern, input impedance, and other properties) can change, within allowable limits, over a wide frequency range without reconstruction. The Nadenenko dipole, or doublet, antenna, the rhombic antenna, and others are used as wide-band antennas in the meter and decameter wave bands. The horn and the spiral antennas are used as wide-band antennas in the centimeter and decimeter bands.
