WebOmnidirectional Antenna Types. The size of an antenna is directly related to the wavelength of the frequency to be received. The most common types used in wireless audio systems are 1/4-wave and 1/2-wave omni-directional antennas, and unidirectional antennas. ¼-Wave . This antenna is one-quarter the size of the desired frequency's wavelength. WebThe helix antenna is a travelling wave antenna, which means the current travels along the …
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".
