Classification: CPC H | IPC H

Claim 0:
1. An antenna unit, comprising:
a first antenna plate having a first interior surface and a first exterior surface;
a second antenna plate having a second interior surface and a second exterior surface, the second antenna plate being spatially disposed from the first antenna plate and the second interior surface of the second antenna plate facing the first interior surface of the first antenna plate;
a glass frame disposed between the first interior surface of the first antenna plate and the second interior surface of the second antenna plate, the glass frame defining an internal cavity;
at least one printed circuit board (PCB);
a first integrated circuit (IC) mounted to the at least one PCB, the first IC configured to at least one of send or receive signals at a first frequency;
a second IC mounted to the at least one PCB, the second IC configured to at least one of send or receive signals at a second frequency, the second frequency being different from the first frequency;
a first waveguide element configured to transmit signals at the first frequency through first waveguide channels between the first antenna plate and the first IC, and
a second waveguide element configured to transmit signals at the second frequency through second waveguide channels between the second antenna plate and the second IC;
wherein the first antenna plate, the second antenna plate, the glass frame, and each of the at least one PCB comprises a material that transmits at least 50% of incident light in the visible spectrum.
