摘要： The multiple polarization loop antenna includes a circularly polarized loop antenna, which may utilize a loop electrical conductor and two signal feedpoints along the loop electrical conductor separated by one quarter of the length of the loop circumference for a signal feedpoint phase angle input difference of 90 degrees. Each of the signal feedpoints may include a loop discontinuity, so that at least one signal source coupled thereto provides circular polarization from the loop electrical conductor. The circularly polarized loop antenna provides an increase in gain and decrease in size relative to the dipole turnstile. It can provide two orthogonal polarizations from two isolated ports, and the polarizations may be dual linear or dual circular.

摘要： The hybrid junction includes four electrically conductive planar windings, circular or rectangular, arranged so as to lie along an imaginary spherical or cylindrical surface. Each of the four electrically conductive windings is rotated from adjacent windings by about forty-five degrees. The four electrically conductive windings are electrically insulated from each other and each include a respective signal port. The hybrid junction automatically splits and/or sorts signals. Signals applied to any port will split equally between the opposite port pairs. One output signal will be in-phase with the input signal, and the other output signal will be shifted by 0 or 180 degrees from the input signal. The input signal is split equally, output coupling may be half power or loose, and there is isolation between the output ports. The hybrid junction operates over a broad bandwidth.

摘要： A method for heating heavy oil inside a production well. The method raises the subsurface temperature of heavy oil by utilizing an activator that has been injected below the surface. The activator is then excited with a generated non-microwave frequency from 0.1 MHz to 300 MHz such that the excited activator heats the heavy oil.

摘要： A method of producing hydrocarbons from a well. The method begins by injecting steam into a well. The bitumen in the formation is then heated with the injected steam, followed by ceasing the injection of steam into the well and then by soaking the bitumen with the injected steam and collecting the heated oil. Steam that has condensed is revaporized by directing RF/MW radiation to the steam allowing for more bitumen to be produced without injecting more steam. In addition, some of the steam could become superheated, wherein the temperature of the superheated steam is greater than the temperature of the steam. The bitumen is heated by the revaporized steam and the superheated steam, followed by soaking the bitumen with the revaporized steam and the superheated steam. Hydrocarbons are then produced from the well.

摘要： The present invention provides a method of producing upgraded hydrocarbons in-situ from a production well. The method begins by operating a subsurface recovery of hydrocarbons with a production well. An RF absorbent material is heated by at least one RF emitter and used as a heated RF absorbent material, which in turn heats the hydrocarbons to be produced. Hydrocarbons are upgraded in-situ and then produced from the production well.
