  • Compact, broadband antennas based on folded, top-loaded broadband dipoles with high-pass tuning elements
    Patent number: 6208306
    Abstract: A compact, electrically-small broadband antenna which combines a folded, top-loaded antenna geometry using broadband radiating elements with a series capacitance applied at the antenna feed is provided. The antenna can be used alone or in combination with a frequency-independent antenna such as a log-periodic dipole array. Additional antenna elements may also be included to improve the transition between the antenna and such a frequency-independent antenna.
