Linearly polarized radial line slot antenna

A helical antenna is an antenna consisting of one or more conducting wires wound in the form of a helix. In most cases, directional helical antennas are mounted over a ground plane, while omnidirectional designs may not be. The feed line is connected between the bottom of the helix and the ground ... For monofilar designs the radiation is linearly polarized parallel to the helix ...
