Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
109 words
An end-fed antenna for a plurality of wave length ranges, at least one of which is in the millimeter range, the antenna comprising: a millimeter range wave guide; an electrically conductive outer tube positioned around said wave guide and forming a coaxial conductor with said wave guide. at least one millimeter wave transmitting antenna positioned on said electrically conductive outer tube and electrically connected to said wave guide; a millimeter wave received system comprising at least a mm-wave receiving antenna, a mixer and an IF-amplifier, said millimeter wave receiving system located on said electrically conductive outer tube for receiving millimeter waves and applying electrical signals to said coaxial conductor.
Claim 2
Dependent Claim
109 words
An end-fed antenna for a plurality of wave length ranges, at least one of which is in the millimeter range, the antenna comprising: a millimeter range wave guide; an electrically conductive outer tube positioned around said wave guide and forming a coaxial conductor with said wave guide. at least one millimeter wave transmitting antenna positioned on said electrically conductive outer tube and electrically connected to said wave guide; a millimeter wave received system comprising at least a mm-wave receiving antenna, a mixer and an IF-amplifier, said millimeter wave receiving system located on said electrically conductive outer tube for receiving millimeter waves and applying electrical signals to said coaxial conductor.
Claim 3
Dependent Claim
16 words
End-fed rod antenna in accordance with claim 1, wherein: said wave guide is a circular waveguide.
Claim 4
Dependent Claim
19 words
End-fed rod antenna in accordance with claim 2 wherein: said circular waveguide is sized to support H 01 waves.
Claim 5
Dependent Claim
53 words
End-fed rod antenna in accordance with claim 1 wherein: the end-fed rod antenna has a base and a top at opposite ends of the end-fed antenna; and said millimeter-wave transmitting antenna is located at said top and that at least one millimeter-wave receiving system is located between said millimeter transmitting antenna and base.
Claim 6
Dependent Claim
53 words
An end-fed rod antenna in accordance with claim 1, further comprising: transmitter-receiver electronic assemblies electrically connected to said wave guide and said coaxial conductor, for propagating millimeter waves into said wave guide, for broadcasting via said millimeter wave transmitting antenna, and for receiving from said millimeter wave receiving antenna on said coaxial conductor.
