Helical antenna having a parasitic element and method of using same |
摘要 |
An efficiently radiating helical antenna includes a conductive helix receiving signals to be radiated at a first end of the conductive helix device for capacitively pulling fields generated by the signals towards a second end of the conductive helix opposite the first end. The device may be a conductive tube inserted into the second end of the conductive helix or a disjointed conductive helix surrounding the conductive helix. This scheme works especially well for a conductive helix having a circumference on the order of one wavelength./!
