Abstract

Disclosed is a guided surface waveguide probe including a charge terminal configured to generate an electromagnetic field and a support apparatus that supports the charge terminal above a lossy conducting medium, wherein the electromagnetic field generated by the charge terminal synthesizes a wave front incident at a complex Brewster angle of incidence (θ i,B ) of the lossy conducting medium.

Claims

exact text as granted — not AI-modified
Therefore, the following is claimed: 
     
         1 . A guided surface waveguide probe comprising:
 a charge terminal configured to generate a guided surface wave comprising an electromagnetic field;   a support apparatus that supports the charge terminal above a lossy conducting medium, wherein the electromagnetic field generated by the charge terminal synthesizes a wave front incident at a complex Brewster angle of incidence (θ i,B ) of the lossy conducting medium; and   a feed network electrically coupled to the charge terminal, the feed network providing a phase delay (Φ) that matches a wave tilt angle (Ψ) associated with the complex Brewster angle of incidence (θ i,B ) in the vicinity of the guided surface waveguide probe.   
     
     
         2 . The probe of  claim 1 , wherein the charge terminal comprises a spherical member. 
     
     
         3 . The probe of  claim 2 , wherein the spherical member is hollow. 
     
     
         4 . The probe of  claim 3 , wherein the spherical member is made of a metal material. 
     
     
         5 . The probe of  claim 1 , wherein the charge terminal comprises multiple spherical members. 
     
     
         6 . The probe of  claim 5 , wherein the spherical members are spaced from each other. 
     
     
         7 . The probe of  claim 6 , wherein the spherical members are hollow. 
     
     
         8 . The probe of  claim 7 , wherein the spherical members are made of a metal material. 
     
     
         9 . The probe of  claim 1 , wherein the charge terminal comprises an ellipsoid member. 
     
     
         10 . The probe of  claim 9 , wherein the ellipsoid member is hollow. 
     
     
         11 . The probe of  claim 10 , wherein the ellipsoid member is made of a metal material. 
     
     
         12 . The probe of  claim 9 , wherein a minor axis of the ellipsoid member is generally vertical. 
     
     
         13 . The probe of  claim 9 , wherein a minor axis of the ellipsoid member is generally horizontal. 
     
     
         14 . The probe of  claim 1 , wherein the charge terminal comprises a toroid member. 
     
     
         15 . The probe of  claim 14 , wherein the toroid member is hollow. 
     
     
         16 . The probe of  claim 15 , wherein the toroid member is made of a metal material. 
     
     
         17 . The probe of  claim 14 , wherein the toroid member is generally horizontal such that a central axis of a central opening of the toroid member is generally vertical. 
     
     
         18 . The probe of  claim 14 , wherein the toroid member is generally vertical such that a central axis of a central opening of the toroid member is generally horizontal. 
     
     
         19 . The probe of  claim 1 , wherein the charge terminal comprises a cylindrical member. 
     
     
         20 . The probe of  claim 19 , wherein the cylindrical member comprises rounded ends. 
     
     
         21 . The probe of  claim 1 , wherein the charge terminal is hollow and comprises an outer surface including multiple openings that enable air to pass through the terminal. 
     
     
         22 . The probe of  claim 1 , wherein the charge terminal comprises a plurality of rods that together define a discontinuous effective surface of the terminal. 
     
     
         23 . The probe of  claim 1 , wherein the feed network comprises a conductive coil. 
     
     
         24 . The probe of  claim 23 , further comprising a feed line connector that electrically couples the conductive coil with the charge terminal. 
     
     
         25 . The probe of  claim 24 , further comprising a stake that electrically couples the conductive coil to the lossy conducting medium.
