WebThe operation mode of helix antenna may give a clue to the change of the half-power beam-width and the gain bandwidth. As is well-known, the radiation pattern of a regular helix is closely related to the ratio between the helix diameter . D. and the operating wavelength λ. Generally, a helical antenna presents a broadside pattern when . D O 0.18 A helical antenna is an antenna consisting of one or more conducting wires wound in the form of a helix. A helical antenna made of one helical wire, the most common type, is called monofilar, while antennas with two or four wires in a helix are called bifilar, or quadrifilar, respectively. In most cases, directional … See more If the circumference of the helix is significantly less than a wavelength and its pitch (axial distance between successive turns) is significantly less than a quarter wavelength, the antenna is called a normal-mode helix. … See more • Telstar See more • "Helical antennas".
