Systems and methods for multi-band concentric helical antennas

A multi-band radiating element comprising:

• a first helical antenna and at least a second helical antenna, wherein the second helical antenna is positioned within the first helical antenna, wherein the first helical antenna has a first frequency band and the second helical antenna has a second frequency band which is not the same as the first frequency band, and wherein the first helical antenna and the second helical antenna are connected to a base.

A method of constructing a multi-band helical antenna system, the method comprising:

• connecting a first helical antenna having a first frequency band to a base having an aperture, wherein the aperture is an area of the base under the antenna;
• and
• connecting a second helical antenna having a second frequency band different from the first frequency band to the base, wherein the second antenna is within the aperture of the base, and the first antenna is within the second antenna.
