Waveguide assembly comprising first and second waveguide portions joined together through a gap interface and communication system formed therefrom

A method of coupling a waveguide assembly, the method comprising:

• slidingly connecting a first waveguide portion and a second waveguide portion, the first waveguide portion having a first end, a second end, and a first waveguide channel extending between the first end and the second end, the first waveguide channel having cross-section dimensions, the first waveguide portion further including a receiving portion configured at the second end, the receiving portion having cross-sectional dimensions that are larger than the cross-sectional dimensions of the first waveguide channel, and the second waveguide portion having a first end, a second end, and a second waveguide channel extending between the first end and the second end, the second waveguide channel having cross-sectional dimensions that are substantially the same as the cross-sectional dimension of the first waveguide channel and having an extending portion at the first end that is complementary to the receiving portion of the second end of the first waveguide portion, wherein the first waveguide portion and the second waveguide portion are configured to connect such that the first waveguide channel and the second waveguide channel form a combined channel, wherein the combined channel includes a gap interface between the first waveguide channel and the second waveguide channel;
• and
• connecting a polarization component to the first end of the first waveguide portion.

A communication system comprising:

• a polarizer;
• a first waveguide portion having a first end and a second end;
• a second waveguide portion having a first end and a second end, wherein the first waveguide portion and the second waveguide portion are coupled at the second end of the first waveguide portion and the first end of the second waveguide portion to define a waveguide channel having a gap interface between the first and second waveguide portions;
• and
• a reflector, wherein the polarizer is coupled to the first end of the first waveguide portion and the reflector is attached to the second end of the second waveguide portion.
