Abstract
A half-mode waveguide, in accordance with a non-limiting example, includes a body having a base wall, a top wall, a first side wall, and a second side wall. The body has a height defined between the base wall and the top wall. A signal channel extends through the body from the first side wall to the second side wall. The signal channel includes a first side wall portion, a second side wall portion, and a base wall portion. The first side wall portion has a first height, and the second side wall portion has a second height that is greater than the first height of the first side wall portion.

A half-mode waveguide comprising:
- a body having a base wall, a top wall, a first side wall, and a second side wall, the body having a height defined between the base wall and the top wall;
- and
- a signal channel extending through the body from the first side wall to the second side wall, the signal channel including a first side wall portion, a second side wall portion, and a base wall portion, the first side wall portion having a first height and the second side wall portion having a second height that is greater than the first height of the first side wall portion.
An automotive radar system comprising:
- a printed circuit board (PCB) formed from a plurality of layers, the PCB including a first surface and a second surface that is opposite the first surface;
- a monolithic microwave integrated circuit (MMIC) mounted to the first surface;
- a radar control module mounted to the second surface of the PCB;
- and
- a half-mode waveguide system extending along the second surface of the PCB connecting the MMIC to the radar control module, the half-mode waveguide system including a half-mode waveguide comprising:
- a body having a base wall, a top wall, a first side wall, and a second side wall, the body having a height defined between the base wall and the top wall;
- and
- a signal channel extending from an inlet defined at the first side wall through the body to an outlet defined at the second side wall, the signal channel including a first side wall portion, a second side wall portion, and a base wall portion, the first side wall portion having a first height and the second side wall portion having a second height that is greater than the first height of the first side wall portion.
