Abstract
A transmission medium consists of a dielectric waveguide shielded by a metal guide. The guide is particularly suitable for providing low insertion loss, convenient transfer of power from one such transmission line to another and for the trouble free handling of high power levels at many hundreds of watts. This type of transmission medium may be used to provide low loss combination of power signals that is low loss, compact while containing the solid state power amplifying elements (MMICs) and capable of high power.
Claims7
A waveguide power combiner having an input and an output comprising:
- a plurality of waveguides for receiving the input, said plurality of waveguides extending in a vertical and a horizontal direction;
- dielectric substrates disposed within said plurality of waveguides in the vertical direction, said dielectric substrates each having a variable thickness ranging from a maximum thickness to a minimum thickness for transmitting power to said waveguides, said dielectric substrates each include a plurality of tapered-slotted antennas, such that at least one antenna is associated with each waveguide;
- and
- means for combining said plurality of waveguides into a reduced number of waveguides, such that said reduced number of waveguides provide the combiner output.
