摘要
A small helical antenna with broad fan radiation pattern provides easy impedance matching and high radiation efficiency. It is composed of a dielectric cylinder, a plurality of radiation conductors arranged on the outer surface of the dielectric cylinder, a matching conductor arranged on the upper inner surface of the dielectric cylinder that cancels inductive reactance, and a plurality of feeder conductors arranged near the radiation conductors on the lower inner surface of the dielectric cylinder and lowering the impedance of the helical antenna.
