Helix Antenna 868MHz

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, it has been widely used in telecommunication to communicate. This antenna has a frequency range of  865MHz to 868MHz with a gain of 1.5dBi depending upon the PCB ground plane. One of the main reasons to use a helix antenna is its low cost and compact size.
