Planar Spiral Antennas

Available from 0.75GHz to 18GHz
The RF Miso planar spiral antenna consists of a metal helix with good conductivity, usually fed by a coaxial cable, the core of which is connected to one end of the helix, and the outer conductor of the coaxial cable is connected to a grounded metal mesh (or plate). There are two polarization modes: linear polarization and circular polarization. Note: Data optimization and customization services are available, please contact RF Miso.
